What exactly are you trying to find?
Answer:
2?
Step-by-step explanation:
seven more than two equals nine because 9-7=2
Less than double of that number: double two is four and less than that is two, well that's what I understood from that. Hopefully it's right.
Answer:
0.9975 = 99.75% probability of getting at least 1 call between eight and nine in the morning.
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
The number of calls received by an office on Monday morning between 8:00 AM and 9:00 AM has a mean of 6.
This means that
Calculate the probability of getting at least 1 call between eight and nine in the morning.
Either you get no calls, or you get at least one call. The sum of the probabilities of these events is decimal 1. Mathematically, we have that:
We want . So
In which
Then
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0025 = 0.9975[tex]
0.9975 = 99.75% probability of getting at least 1 call between eight and nine in the morning.
