Question

A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P ( red or blue)

Answer 1

5/8

Explanation:

To find the combined probability we will write as a fraction with the number of occurrences for the specified conditions.

Here, we have 16 marbles total (as 6 + 6 + 4 = 16) and we want to find the probabiliy of choosing either a red or blue marble out of the 16. There are 10 marbles that are either red or blue (as 16 - 6 = 10) so the fraction would be 10/16. However, we still need to get this simplest form.

`(10)/(16) = (5)/(8)`

As we cannot simplify 5/8 any further, this is the final answer.
