Suppose that 50 % of all babies born in a particular hospital are boys. If 6 babies born in the hospital are randomly selected, what is the probability that at most 2 of them are boys?
Added by Raven O.
Step 1
In a binomial distribution, we have a fixed number of independent trials (in this case, 6 babies), each of which results in a success (a boy) with probability p (in this case, 0.5) or a failure (a girl) with probability 1-p. The probability of getting exactly k Show more…

Suppose that 50% of all babies born in a particular hospital are boys. If 6 babies born in the hospital are randomly selected, what is the probability that at least 2 of them are boys? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places. (If necessary, consult a list of formulas.)

Suppose that 50% of all babies born in a particular hospital are boys. If 8 babies born in the hospital are randomly selected, what is the probability that at most 1 of them are boys? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.

Assume that the probability of any newborn baby being a boy is 1/2 and that all births are independent. If a family has three children (no twins), what is the probability of the event that they are all boys?
