a) make a probability distribution
b) wht is the probability that number of member in a family are less than 5?
c) what is the probability that number of member in a family are more than 8?​

Answer 1

Answer:

solved

Step-by-step explanation:

a) probability distribution

0 - 5    :    4

5 - 10    :    14

10 - 15    :   7

total        : 25

b) what is the probability that number of member in a family are less than 5?

P(x less than 5) = 4/25 = 0.16

c) what is the probability that number of member in a family are more than 8?​

p(x More tan 8) = 8/25 = 0.32
