If answer is correct, i will give brainiest !!

Step-by-step explanation:

The probability that Aaron goes to the gym on exactly one of the two days= pro. that he goes on Saturday or pro. that he goes on Sunday

Prob. he goes on Saturday =0.8 while prob. that he goes on Sunday but not on Saturday = 0.9.

The prob. that Aaron goes to the gym either of the two days= 0.8 + 0.9 = 1.7

This can also be expressed as 16(1 + 3)

Step-by-step explanation:

For this we look for the greatest common factor to put on the outside. Each term can be evenly divided by 16. So we take 16 out and divide each term by 16 in the parenthesis.
