1. Problem Description
The problem asks us to find the number of times we would expect a spinner to land on a number less than 7 if it is spun 250 times. The spinner has 10 equally likely outcomes labeled 1 through
1
0.
2. Solution Steps
First, we need to determine the probability of the spinner landing on a number less than 7 in a single spin. The numbers less than 7 are 1, 2, 3, 4, 5, and
6. There are 6 such numbers.
Since there are 10 equally likely outcomes, the probability of landing on a number less than 7 is or .
Next, we need to find the expected number of times the spinner will land on a number less than 7 when spun 250 times. This is calculated by multiplying the probability of landing on a number less than 7 in a single spin by the total number of spins:
