In a graph of 1,500 people, 585 has blood type a, 165 have blood type b, 690 have blood type o, and 60 have blood type ab. what is the probability that a person chosen at random from this group has type b blood?

a. p(b) = 4%

b. p(b) = 11%

c. p(b) = 39%

d. p(b) = 46%

Ok, so we are finding probability so first, we need to know the specific categories we have to address. The question is asking about type B blood and we have 165 who have type B blood out of 1500. To find probability you need to divide the number of events, (in this case, blood types), by the number of possible outcomes. So 165/1500 is 0.11 which goes into 11% of a chance that a randomly pulled person will have type B blood! Hope I helped, if you have any questions, feel free to ask!
