Question

1. In some cultures it is good to have feet smane

cultures it is good to have feet smaller than size 5. If the probability of having feet
smaller than size 5 is 0.12, find the probability that the
size 5 IS 0.12, find the probability that the 3rd person you stop walking down the
street is the first to have a foot size smaller than 5.​

Answer 1

.093 .

Explanation:

the probability of having feet smaller than size 5 is 0.12,

the probability of having feet longer than size 5 will be 1 - 0.12 = 0.88

The probability that the 3rd person walking down the

street is the first to have a foot size smaller than 5

= probability of first person having feet longer than size 5 x probability of second person having feet longer than size 5 x probability of third person having feet smaller than size 5

= .88 x .88 x .12

= .093 .
