Find the total number of outcomes when choosing a flavor of ice cream. (Vanilla, strawberry, chocolate, butterscotch) a topping (Strawberry or whipped) and a container (come or cup).

16

Step-by-step explanation:

4 flavors

2 toppings

2 containers

4x 2 = 8

8x2=16

Sales of the chocolate ice cream is 45%, 30% for strawberry and 25% (100%-45%-30%) of vanilla.

Percentages of cone sales for chocolate, strawberry and vanilla are 75%, 60% and 40%respectively.

A. Probability chocolate chosen: 45%=0.45

B. Probability strawberry chosen: 30%=0.30

C. Probability vanilla chosen:25%=0.25

D. Probability ice cream on a cone: 75%*45%+60%*30%+40%*25%

=0.75*0.45+0.60*0.30+0.40*0.25

=0.3375+0.18+0.1

=0.6175

E. Probability ice cream in a cup: 1 - Probability ice cream in a cone

=1-0.6175

=0.3825

Probability that the ice cream sold on a cone and was strawberry flavoured is : 30%*60%

=0.30*0.60

=0.18
