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.
Homework Answers
We have given,
=0.0039 + 0.0313
=0.0352
| Therefore, the probability that at most 1 of them are boys =0.04 |
