f) Under 21 : 2196

21-25 : 2057

26-30 :1179

Over 35 : 223

A student from the community college is selected at random. The events A and B are defined as follows. A = event the student is between 21 and 35 inclusive B = event the student is 26 or over Determine the number of outcomes that comprise the event (A and B).

please explain

Explanation / Answer

A = event the student is between 21 and 35 inclusive
B = event the student is 26 or over

Then

(A and B) is the event that satisfies both A and B.

Hence, we refer to the age group 26 to 35.

Hence,

n(A and B) = n(26-30) + n(31-35) = 1179 + 832 = 2011 [ANSWER]
