The blood groups of 200 people are distributed as follows: 40 have type A blood, 75 have type B blood, 60 have type O blood, and 25 have type AB blood. If a person from any of the group is selected at random, what is the probability that this person has an O blood type? How about the AB blood type?
Answers
Answer:
probability of o blood type is 3/10
Given
o blood type of people have 60
blood groups of people are 200
then,
probability of o blood is 60/200
p of o blood is 3/10
Given : The blood groups of 200 people are distributed as follows: 40 have type A blood, 75 have type B blood, 60 have type O blood, and 25 have type AB blood. If a person from any of the group is selected at random,
To Find : probability that this person has an
O blood type
AB blood type
Solution:
Total = 200
Type A = 40
Type B = 75
Type O = 60
Type AB = 25
probability that person has O blood type = 60/200
= 3/10
= 0.3
probability that person has AB blood type = 25/200
= 1/8
= 0.125
