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

Answer:

.093 .

Step-by-step 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 .
