There are 52 contacts in your phone. The only family members' numbers you have are your dad's, mom's, and brother's. What are the odds of selecting a number in your phone that is not your family? Write your answer as 1:2 which is reduced as much as possible.

Answers

Answer:

49:52

Step-by-step explanation:

Given that:

Total number of contacts on phone = 52

Family members in phone book : dad, mom, brother

Total number of family members = 3

Hence, non family members = 52 - 3 = 49

Number of family members to total phone contact

Selecting a contact that is not a family member :

49 : 52

Answer:

the answer is 49:3 :)

The y intercept is 32 :)

Answer:

32

Step-by-step explanation:

slope:

m = (y₂ - y₁) / (x₂ - x₁)

   = (32 - 14) / 0 - (-6)

   = 18 / 6

   = 3

y-intercept, use any point to determine b, let's use (2, 38) :

y = mx + b

38 = 3(2) + b

38 = 6 + b

b = 32

QUESTION 8
Solve the problem that involves probabilities with events that are not mutually exclusive.
Consider a political discussion group consisting of 8 Democrats, 3 Republicans, and 7 Independents. Suppose that two
group members are randomly selected, in succession, to attend a political convention. Find the probability of selecting
an Independent and then a Democrat.
14/81, 25/153, 7/306/ or 4/153?

Answers

Answer:

Option (2).

Step-by-step explanation:

Number of Democrats in a political discussion = 8

Number of Republicans = 3

Number of independents = 7

Total members in the discussion = (8 + 3 + 7)

                                                       = 18

Probability of selecting an independent = [tex]\frac{7}{18}[/tex]

Remaining members after selecting one independent = 17

Probability of selecting a Democrat = [tex]\frac{8}{17}[/tex]

Probability of selecting a Republican then a Democrat = [tex]\frac{7}{18}\times \frac{8}{17}[/tex]

                                                                                           = [tex]\frac{28}{153}[/tex]

Therefore, Option (2) will be the answer.
