Peanut allergies among children. about 2% of children in the united states are allergic to peanuts. choose three children at random and let the random variable xx be the number in this sample who are allergic to peanuts. the possible values xx can take are 0, 1, 2, and 3.

what is the conditional probability that exactly two of the children will be allergic to peanuts, given that at least one of the three children suffers from this allergy?

(round your answer to six decimal places.)

p(x=2|x⩾1)p(x=2|x⩾1) =

P(X=2|X≥1) = 0.0199973.

Step-by-step explanation:

The chance that each of the three children is allergic to peanuts is independent. Each with a chance of 2% = 0.02.

X follows a binomial distribution with

.

The event includes

In other words, implies that .

.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
