Question

ignoring twins and other multiple births, assume babies born at a hospital are independent events with the probability that a baby is a boy and the probability that a baby is a girl both equal to 0.5. if the first 9 children born are girls, what is the probability the next born child is a boy?

0.50
0.75
0.80
0.99
cannot tell based on this information

Explanation:

Step1: Recall independent - event property

Since the births of babies are independent events, the outcome of previous births does not affect the outcome of the next birth.

Step2: Determine the probability

The probability that a baby is a boy is given as 0.5, and this probability remains the same regardless of the genders of previous babies.

Answer:

0.50
