Problem-

An ice cream vendor sells three flavors: chocolate, strawberry, and vanilla. Forty five percent of the sales are chocolate, while 30% are strawberry, with the rest vanilla flavored. Sales are by the cone or the cup. The percentages of cones sales for chocolate, strawberry, and vanilla, are 75%, 60%, and 40%, respectively. For a randomly selected sale, define the following events:

A₁ = chocolate chosen
A₂= strawberry chosen
A₃= vanilla chosen
B  = ice cream on a cone
B¯ = ice cream in a cup

Find the probability that the ice cream was sold on a cone and was vanilla flavor.

Additional information-

The problem relates to Basic Statistics and it is about computing the sales of ice cream flavors of chocolate, vanilla and strawberry. The problem is to determine the probability of selling an ice cream in cone with vanilla flavor.
