Answer:
a) 0.8
b)0.05
c)0.15
d)0.2
e)0.85
Step-by-step explanation:
a)
The probability of selecting student can be computed as
P(S)=number of students in survey/total number of individuals
P(S)=800/1000=0.8
b)
The probability of selecting faculty member can be computed as
P(F)=number of faculty member in survey/total number of individuals
P(F)=50/1000=0.05
c)
The probability of selecting administrator can be computed as
P(A)=number of administrator in survey/total number of individuals
P(A)=150/1000=0.15
d)
The probability of selecting faculty member or administrator can be computed as
P(A or F)=P(A)+P(F)-P(A∩F) as A and F are mutually exclusive so P(A∩F) will be zero,
P(A or F)=P(A)+P(F)=0.15+0.05=0.2
e)
The probability of selecting except administrator can be computed as
P(A')=1-P(A)=1-0.15=0.85
