The prior probabilities for events A1, A2, and A3 are P(A1) = 0.50, P(A2) = 0.20, and P(A3) = 0.30. The conditional probabilities of event B given A1, A2, and A3 are P(B | A1) = 0.50, P(B | A2) = 0.40, and P(B | A3) = 0.20. (Assume that A1, A2, and A3 are mutually exclusive events whose union is the entire sample space.)
Required:
Compute P(B â© A1), P(B â© A2), and P(B â© A3).
Answers
Answer:
P( B∩ A₁ ) = 0.25
P( B∩ A₂ ) = 0.08
P( B∩ A₃ ) = 0.06
Step-by-step explanation:
As we know that
P( B∩ A₁ ) = P( B| A₁) × P(A₁)
P( B∩ A₂ ) = P( B| A₂) × P(A₂)
P( B∩ A₃ ) = P( B| A₃) × P(A₃)
As we have
P(A₁) = 0.50, P(A₂) = 0.20, and P(A₃) = 0.30.
P(B | A₁) = 0.50, P(B | A₂) = 0.40, and P(B | A₃) = 0.20
⇒P( B∩ A₁ ) = P( B| A₁) × P(A₁)
= 0.50(0.50)
= 0.25
⇒P( B∩ A₁ ) = 0.25
Now,
⇒P( B∩ A₂ ) = P( B| A₂) × P(A₂)
= 0.40(0.20)
= 0.08
⇒P( B∩ A₂ ) = 0.08
Now,
⇒P( B∩ A₃ ) = P( B| A₃) × P(A₃)
= 0.20(0.30)
= 0.06
⇒P( B∩ A₃ ) = 0.06
∴ we get
P( B∩ A₁ ) = 0.25
P( B∩ A₂ ) = 0.08
P( B∩ A₃ ) = 0.06

Step-by-step explanation:
The spinner has 6 sections.
There are 2 vowels, A and U.
There is only one section with a K.
p(event) = (number of desired outcomes)/(total number of outcomes)
p(vowel) = 2/6 = 1/3
p(k) = 1/6
Each spin is an event. The two events are independent, so the probability of the two events is the product of the individual probabilities.
p(vowel, then K) = p(vowel) * p(k)
p(vowel, then K) = 1/3 * 1/6 = 1/18

Calculate the distance (d) using the distance formula
The expression gives the distance between the points (4, 6) and (7,-3) is . √(4-7)² + (6 +3)²
The correct option is Option C.
What is Distance Formula?The formula for measuring distance is . Any two points in 2D space that have the coordinates (x₁, y₁) for the first point and (x₂, y₂) for the second point can be used in this way.
The Euclidean distance formula is another name for the formula used to calculate the separation between two points on a two-dimensional plane.
Given:
The points are (4, 6) and (7, -3) respectively.
Put points in the formula:
Formula: distance= √(x_2-x_1)²+(y_2-y_1)²
substituting we get,
√(4-7)² + (6 +3)²
, which is the required expression.
Hence, The expression gives the distance between the points (4, 6) and (7,-3) is . √(4-7)² + (6 +3)²
The correct option is Option C.

Answers
Answer:
58.3 in^2
Step-by-step explanation:
The shape is made of a rectangle, a triangle and a semi-circle. We can find the area of each section and then add them together to get the area of the whole shape.
The area of a rectangle is length x width.
The length of the rectangle is 11 inches and the width is 4 inches
11 times 4 is 44
so the area of the rectangular section is 44 inches squared
To find the semi circle, I would find the area of a circle with an equal radius, and then divide that by 2.
The area of a circle is pi times the radius squared.
The radius here is 2 inches because it says diameter is 4 inches
2 squared is 4 and 4 times pi is ~12.6
So the area of the semi-circle section is ~6.3 inches squared
The area of a triangle is 1/2 base x height
Both the base and height of this triangle are 4 inches long (15-11=4)
so 1/2(4) times 4 is 8
so the area of the triangle section is 8 inches squared
Add them all together and you get 58.3 inches squared

Hello!

We can find the value of t using the slope formula:
[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Plug in the given slope and coordinates into the appropriate places:
[tex]5 = \frac{2-t}{3-1}[/tex]
Simplify:
[tex]5 = \frac{2-t}{2}[/tex]
Multiply both sides by 2 to begin isolating for t. Simplify and solve for t:

Car repairs: Let be the event that a new car requires engine work under warranty and let be the event that the car requires transmission work under warranty. Suppose that ,P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .
(a) Find the probability that the car needs work on either the engine, the transmission, or both.
(b) Find the probability that the car needs no work on the engine.
Answers
Answer:
a) 0.11 = 11% probability that the car needs work on either the engine, the transmission, or both.
b) 0.9 = 90% probability that the car needs no work on the engine.
Step-by-step explanation:
P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .
This means that:
Only engine: 0.1 - 0.01 = 0.09
Only transmission: 0.02 - 0.01 = 0.01
Both engine and transmission: 0.01
(a) Find the probability that the car needs work on either the engine, the transmission, or both.
0.09 + 0.01 + 0.01 = 0.11
0.11 = 11% probability that the car needs work on either the engine, the transmission, or both.
(b) Find the probability that the car needs no work on the engine.
Probability of needing work on engine:
0.09 + 0.01 = 0.1
Not needing:
1 - 0.1 = 0.9
0.9 = 90% probability that the car needs no work on the engine.
