Answer 1

Answer #1

P(girl)= P(Boy) = 0.50

X ~ Binomial (n,p)

Where n = 3 , p = 0.50

P(X) = ⁿC_x p^x (1 -p )^n-x

Where X be the number of boys.

P( X = 2) = ³C₂ 0.5² 0.5

= 0.375

We considered a town with two hospitals. In the large hospital about 45 babies are born each day, and in the smaller hospital about 15 babies are born each day. We were interested in guessing which hospital would have on the average the largest number of days with the property that more than 60 percent of the children born on that day are boys. The probability of a boy being born is 0.5 For each hospital find the expected number...
