The answer to this problem is: m^2+8m-5
Answer:
0.082
Step-by-step explanation:
Total number of clients = 4
From past experience, the agent knows that the probability of making a sale on any appointment is one out of five = 1/5.
This shows that there are only two possible outcomes, success or failure. It is either she makes a sale on an appointment or she fails to make a sale on the appointment. Therefore, we can use binomial distribution.
For binomial distribution,
P(x=r) = nCr × q^(n-r) × p^r
p = probability of making a sale on any appointment = 1/5 = 0.2
q = probability of not making a sale on any appointment = 1 -1/5 = 0.8
n = 5
x = 3
P(x=3) = 5C3 × 0.8^2 × 0.2^3
= 10×0.6724× 0.012167 =0.082
