Step-by-step explanation:

=−2y+10+2y+−8

=(−2y+2y)+(10+−8)

For the answer to the question above, first you have to do is to take the number of days d that the temperature was above 90 in April, divide by 30, the total number of days in April, and then multiply by 100. probability = d/30 * 100

Probability = 5/30 * 100
                  = 16.67

16.67 is the probability. I hope this helps.
