Answer:
J=12
Step-by-step explanation:
(2/3)*j = 8 // - 8
(2/3)*j-8 = 0
2/3*j-8 = 0 // + 8
2/3*j = 8 // : 2/3
j = 8/2/3
j = 12

Answer: 0.04854
Step-by-step explanation:
This is calculated by using the poisson distribution formula calculator. We first have to calculate the average number of success for the given hour then further calculate the poisson Probability for the question.
Average number of customers in first four hours = (4/12) * 120 = 40.
Randomly expected number of customers in First four hours = 35
Hence we input This randomly expected number of customers and average number of customers in our poisson calculator.
P(x=35) = 0.04854
