Question

a box is filled with 9 red crayons, 2 blue crayons, and 5 yellow crayons. a crayon is chosen at random from the box. find the probability that it is a red or a blue crayon. write your answer as a fraction.

Explanation:

Step1: Calculate total number of crayons

There are 9 red, 2 blue, and 5 yellow crayons. So total number of crayons is \(9 + 2 + 5 = 16\).

Step2: Calculate number of red or blue crayons

Number of red or blue crayons is \(9 + 2 = 11\).

Step3: Calculate probability

Probability is the number of favorable outcomes (red or blue) divided by total number of outcomes. So probability \(P=\frac{11}{16}\).

Answer:

\(\frac{11}{16}\)
