Question

A cube numbered 1-6 is rolled. What is the probability of rolling a number less than 4 or an even number?

A. 1
B. 5/6
C. 1/3
D. 1/6

Answer 1

To find the probability of rolling a number less than 4 or an even number, we count the favorable outcomes and divide by the total number of possible outcomes.

Step-by-step explanation:

To find the probability of rolling a number less than 4 or an even number, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.

There are three numbers less than 4: 1, 2, and 3. There are three even numbers: 2, 4, and 6. However, since 2 is already counted in the numbers less than 4, we only need to consider 4 and 6 as additional even numbers. So, the total number of favorable outcomes is 4 (1, 2, 3, 4, and 6) out of 6 possible outcomes.

The probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes: 4/6.
