A random variable X has a Poisson distribution with a mean of 3. What is the probability that X P(1≤X≤3) ?.

P(1≤X≤3) = 0.5974

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.

Mean of 3

This means that

P(1≤X≤3) ?

So

So

i am not sure :

step-by-step explanation:

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m
