The probability distribution for the rate of return on an investment is

babymother [125]

Answer:

a)0.7

b) 10.03

c) 0.0801

Step-by-step explanation:

Rate of return Probability

9.5 0.1

9.8 0.2

10 0.3

10.2 0.3

10.6 0.1

P(Rate of return is at least 10%)=P(R=10)+P(R=10.2)+P(R=10.6)

P(Rate of return is at least 10%)=0.3+0.3+0.1

P(Rate of return is at least 10%)=0.7

Expected rate of return=E(x)=sum(x*p(x))

Rate of return(x) Probability(p(x)) x*p(x)

9.5 0.1 0.95

9.8 0.2 1.96

10 0.3 3

10.2 0.3 3.06

10.6 0.1 1.06

Expected rate of return=E(x)=sum(x*p(x))

Expected rate of return=0.95+1.96+3+3.06+1.06=10.03

variance of the rate of return=V(x)= $sum(x^2p(x))-[sum(x*p(x))]^2$

Rate of return(x) Probability(p(x)) x*p(x) x²*p(x)

9.5 0.1 0.95 9.025

9.8 0.2 1.96 19.208

10 0.3 3 30

10.2 0.3 3.06 31.212

10.6 0.1 1.06 11.236

sum[x²*p(x)]=9.025+19.208+30+31.212+11.236=100.681

variance of the rate of return=V(x)=sum(x²*p(x))-[sum(x*p(x))]²

variance of the rate of return=V(x)=100.681-(10.03)²

variance of the rate of return=V(x)=100.681-100.6009

variance of the rate of return=V(x)=0.0801

So I think it’s D. So you’ll do 5 x 5 x 5 = 125 then x 2 = 250
