The blood groups of 200 people is distributed as follows: 50 have type “A” blood, 65 have type “B” blood, 70 have “O” blood type, and 15 have type “AB” blood. If a person from this group is selected at random, what is the probability that this person has “O” blood type? Round to the nearest hundredths place if a fraction. . [Note, if your calculated value is not identical to one of the values below, but within plus or minus 0.05 of an answer below, assume it’s a rounding error and select the answer that is closest to your calculated value.]
