Question

A six-sided die with sides labeled 1 through 6 will be rolled once. Each number is equally likely to be rolled.

What is the probability of rolling a number greater than 2?

Answer 1

Answer: 2/3

Step-by-step explanation

Event space = set of things we want to happen

Sample space = set of all possible outcomes

Event space = {3,4,5,6}

Sample space = {1,2,3,4,5,6}

The event space is a subset of the sample space.

There are A = 4 items in the event space out of B = 6 items in the sample space.

A/B = 4/6 = 2/3 is the probability of rolling a number greater than 2.

2/3 = 0.6667 = 66.67% approximately.
