Answer:

a. Yes. It is a probability density function because \sum f(x) =1

. b. probability MCC will obtain more than 30 new clients=P(40)+P(50)+P(60)= 0.20+0.35+0.20=0.75

c. probability MCC will obtain fewer than 20 new clients= P(10)= 0.05

d.

x f(x) x*f(x) x*x*f(x)

10 0.05 0.5 5

20 0.1 2 40

30 0.1 3 90

40 0.2 8 320

50 0.35 17.5 875

60 0.2 12 720

1 43 2050

expected value = \sum xf(x) = 43

Variance = 2050-43^2= 201
