Please answer all parts.

In September (30 days), the temperature in a particular city reached 100°F on 24 days. Also, measureable rain fell at the city's airport on 7 days, and on 2 days, both events occurred a) On how many days did at least one of the events occur? b) On how many days did the temperature reach 100°F without measurable rain? c) On how many days did the temperature not reach 100°F and rain did not fall? What formula should be used to solve the problem? O A. (AUB) = n(A) + n(B) OB. n(AB)= n(A)- n(B) + n(AUB) OC. n(AUB) = n(A) + n(B) - n(ANB) OD. (ANB) = n(A) - n(B)+ n(ANB) a) At least one of the events occurred on 1 day(s), (Simplify your answer) b) The temperature reached 100°F without measurable rain on (Simplify your answer.) day(s). day(s). c) The temperature did not reach 100°F and rain did not fall on (Simplify your answer.)
