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
Sin(θ - 180)
sin(θ)cos(180) - cos(θ)sin(180)
sin(θ)[-1] - cos(θ)[0]
-sin(θ) - 0
-sin(θ)
