Question

Assume each newborn baby has a probability of 0.49 of being female. What is the probability of a newborn baby being male?

1) 0.49
2) 0.51
3) 0.50
4) Cannot be determined

Answer 1

The probability of a newborn baby being male is 0.51, which is found by subtracting the probability of being female (0.49) from 1, the total of all probabilities for a given event.

Step-by-step explanation:

The probability of a newborn baby being male, given that the probability of being female is 0.49, is simply the remaining probability which must add up to 1. Since these are the only two possible outcomes, if the probability of being female is 0.49, then the probability of being male is 1 - 0.49 = 0.51. Hence, the correct answer is option 2) 0.51. This is because probabilities of all possible outcomes in a sample space must sum to 1, and there are only two outcomes in this scenario, male or female.
