Question : A) what is the probability that the student selected at random got a B or A grade ?
B) is part A situation mutually exclusive?
Explanation / Answer
SolutionA:
P(A) grade=favorabe events/total
=7/11
P(B)=1/11
the student selected at random got a B or A grade
=P(A)+P(B)
=7/11+1/11
=8/11
=0.7272
SolutionB:
part A situation mutually exclusive
yes mutually exclusive.
since P(A and B)=0 in the above case.
No intersection region.
