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: a. chocolate chosen b. strawberry chosen c. vanilla chosen d. ice cream on a cone e. ice cream in a cup find the probability that the ice cream was sold on a cone and was strawberry flavor

0.18.

Step-by-step explanation: Let us define the following events

A= event that chocolate chosen,

B=event that strawberry chosen,

C=event that vanilla chosen,

D=event of choosing ice-cream on a cone

and

E=event of choosing ice-cream on a cup.

Then, according to the given information, we have

P(A)=0.45, P(B)=0.30, P(C)=0.25, P(A\D)=0.75, P(B\D)=0.60 and P(C\D)=0.40.

Therefore, the probability that the ice-cream was sold on a cone and was strawberry flavour is given by

Thus, the required probability is 0.18.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
