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

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
