How would i solve this

Answer 1

"either type A or type AB blood" so to find the # of people who fit this description, simply add up all the type A and type AB

then, to find the probability of getting an A or AB person, simply divide by the total # of people in the sample

Answer 2

so 150/73?

Answer 3

the type A/AB people go in the numerator, so the other way around

73/150
