Solution

Solution Steps

Step 1: Identify the total number of spins

From the problem, Maya spun the spinner 40 times.

Step 2: Determine the number of favorable outcomes for red or blue

The number of red spins is 12, and the number of blue spins is 7. Therefore, the total number of favorable outcomes for red or blue is: \[ 12 + 7 = 19 \]

Step 3: Calculate the experimental probability

The experimental probability of landing on red or blue is the number of favorable outcomes divided by the total number of spins: \[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of spins}} = \frac{19}{40} \]
