Question

Find each probability for one roll of a number cube:

P(even)
P(1 or 2)
A) 1. 1/2 2. 1/6
B) 1. 1/6 2. 1/2
C) 1. 1/3 2. 1/4
D) 1. 1/4 2. 1/3

Answer 1

The probability of rolling an even number on a number cube is 1/2, and the probability of rolling a 1 or 2 is 1/6.

Step-by-step explanation:

P(even) means the probability of rolling an even number. Since there are 3 even numbers on a number cube (2, 4, and 6), and there are 6 total numbers, the probability would be 3/6 or 1/2.

P(1 or 2) means the probability of rolling a 1 or a 2. Since there is only 1 outcome that is either 1 or 2, and there are 6 total outcomes, the probability would be 1/6.
