The average number of customers arriving at an ATM machine is 27 per hour during lunch hours. Use equation to denote the number
of arrivals in a 5 minute time interval. Assume the customers arrive independently and the number of arrivals within each 5 minutes follows a Poisson distribution. Keep at least 4 decimal digits if the result has more decimal digits. The probability that exactly 2 customers arrive in a given 5 minute interval is closest to
The probability that exactly 2 customers arrive in a given 5 minute interval = 0.2667
Step-by-step explanation:
Given -
The average number of customers arriving at an ATM machine is 27 per hour during lunch hours. then the average number of customers arriving at an ATM machine n a 5 minute time interval = = 2.25
average number of customers arriving at an ATM machine n a 5 minute time interval = 2.25
Let X denote the no of customer arrivals in a 5 minute time interval
The probability that exactly 2 customers arrive in a given 5 minute interval =
Both of the Billy’s parents (calling the parent billy) being tall is a recessive trait therefore both Billy’s parents has to have at least one recessive trait to make a tall child. Billy’s genotype would be way tt (aka recessive, recessive).
