The answer is B.
165/1500 = 0.11

Answer: P(B) = 11%

Step-to-step explanation:-

The total number of people in a group = 1,500

The number of people have blood type B = 165

The probability that a person chosen at random from this group has type B blood is given by :-

\(\text{P(B)}=\frac{\text{favorable outcomes}}{\text{total outcomes}}\\\\\Rightarrow\text{P(B)}=\frac{165}{1500}\\\\\Rightarrow\text{P(B)}=0.11\)

In percent, the  probability that a person chosen at random from this group has type B blood is given by :-

\(\text{P(B)}=0.11\times100\\\\\Rightarrow\text{P(B)}=11\%\)
