Answer:
1.3125
Step-by-step explanation:
Given that our random variable follows a Poisson distribution
Evaluate the formula at
#since
The mean and variance of the Poisson distributed random variable is equal to :
#By property variance:
The expectation is 1.3125
Given:
The graph of a function.
To find:
The zeros of this function on the graph.
Solution:
We know that, zeros are the values at which the values of the function is 0. It means, the points where the graph of function intersect the x-axis are know as zeros of the function.
From the given graph it is clear that, the graph intersect the x-axis at two points.
Therefore, the marked points on the below graph are the zeros of the function.
