Asurvey find that 61% of people are married. they ask the same group of people and 75% of them have at least one kid. if 48% are married and have one kid what is probability that a person in a survey is married or has a child?

22/25

Step-by-step explanation:

The overlap between the 61% and the 75% is the 48%, which means that 13% of the people are married and have no kids (61-48=13)

The 75% includes the people who have one or more kids, and the people who have one or more kids and are married.

Now all we have to do is 13% + 75% = 88% = 22/25
