Mabel is the costume manager for a large theater company. She has 20 different hats,
including 4 pork pie hats.
What is the probability that a randomly chosen hat from Mabel's inventory will be a pork pie
hat?
Write your answer as a fraction or whole number.
P(pork pie hat) =

4/20 or 1/5 being simplified

Step-by-step explanation:

The experimental probability of rolling a 1 is:

The experimental probability of rolling a 2 is:

The experimental probability of rolling a 3 is:

The experimental probability of rolling a 4 is :

The experimental probability of rolling a 5 is :

The experimental probability of rolling a 6 is:

We are given the occurrence of numbers on rolling a number cube as:

         Number----Occurences

            1---------------51

           2--------------47

           3--------------49

           4--------------51

           5--------------50

           6--------------45

This means that the experimental probability of rolling a 1 is:

Ratio of number of times 1 come up and the total number of occurrence.

The total number of occurrence are: 51+47+49+51+50+45=293

This means that the experimental probability of rolling a 1 is:

Similarly we can solve for others.
