Customers arrive at a rate of 24 people per hour to a bank. Assume that the number of customers arriving can be described using the Poisson distribution. What is the probability that exactly 20 customers arrive in the next hour

5.57% probability that exactly 20 customers arrive in the next hour

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which

x is the number of sucesses

e = 2.71828 is the Euler number

is the mean in the given interval.

24 people per hour to a bank.

This means that

What is the probability that exactly 20 customers arrive in the next hour

This is P(X = 20).

5.57% probability that exactly 20 customers arrive in the next hour

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
