https://prnt.sc/tukf1a How would i solve this

Vocaloid:

"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

iosangel:

so 150/73?

Vocaloid:

the type A/AB people go in the numerator, so the other way around 73/150

iosangel:

https://prnt.sc/tukk6n so i wouldnt have to divide that d would be my answer?

Vocaloid:

yeah, since the answer choices are fractions you can stop at D
