There are 41 individuals in a grocery store, of which 18 are female. the total number of individuals who are 30 years old or older is 24 of which 10 are female. If an individual is randomly selected, what is the probability that they are either male or 30 years or older?
Pr(male or 30+)=pr(male)+pr(30+)-pr(male and 30+)
= 23/41+24/41-14/24
