sixty-two percent of pet owners say they consider their pet to be their best friend. you randomly select 12 pet owners and ask them if they consider their pet to be their best friend. find the probability that the number who say their pet is their best friend is (a) exactly nine, (b) at least eight, and (c) at most three.

Is this like 3 separate questions, or is it like
one all together with one answer?

Let’s say the side BC is extended till D

1) measure of angle ACD = 105° ( angle ACD is exterior angle)
45 + 60 = 105
2) I found the answer by adding the values of Angle A and Angle B or by using the exterior angle property.
3) I observed that exterior angle property can be used here. Exterior angle property is that an exterior angle of a triangle is equal to the sum of the opposite interior angles.
