Final answer:

The probability of selecting a red cap is 0.45 or 45%.

Step-by-step explanation:

To find the probability of selecting a red cap, we need to determine the number of red caps available and the total number of caps. There are 9 red caps out of a total of 20 caps at the party. So, the probability of selecting a red cap is:

P(Red) = Number of Red Caps / Total Number of Caps P(Red) = 9 / 20 = 0.45 or 45%

9 out of 20. 9/20. Because since there are 9 red caps and the total are 20, that means that out of the 20, only 9 of them are red.
