F and R represent valid functions. The first two choices.
Answer:
56.65% probability that more than 3 customers arrive during 15 minutes
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, which is the same as the variance. The standard deviation is the square root of the variance.
Standard deviation of 2 customers per 15-minutes.
So
What is the probability that more than 3 customers arrive during 15 minutes
Either three or less customers arrive, or more than 3 do. The sum of these probabilities is decimal 1. Mathematically, we have that:
We want P(X > 3). So
In which
56.65% probability that more than 3 customers arrive during 15 minutes
