Answer 1

First, we need to find the total number of caps that are NOT red, which can be calculated by subtracting the number of red caps from the total number of caps:

Total number of caps NOT red = Total number of caps - Number of red caps
Total number of caps NOT red = 70 - 21
Total number of caps NOT red = 49

Next, we can calculate the probability of selecting a cap that is NOT red by dividing the total number of caps that are NOT red by the total number of caps:

Probability of selecting a cap NOT red = Total number of caps NOT red / Total number of caps
Probability of selecting a cap NOT red = 49 / 70
Probability of selecting a cap NOT red = 0.7

Therefore, the probability of selecting a cap that is NOT red is 0.7 or 70%.
