With a mean of λ , the probability mass distribution (pmf) is given by
for λ = 4, and k<2 (i.e. k=0 or 1)
P(k<2, λ )=P(k=1, λ ) + P(k=1, λ )
=0.01832+0.07326
=0.09158 (to the fifth place of decimal)
Note: Poisson processes have no memory, so 2 calls in first hour has the same probability as 2 calls in any other hour.
Answer: 321q = z
This is the same as z = 321q
The term "product" means "result of multiplying two or more values"
For example, the product of 2 and 3 is 2*3 = 6
Writing 321q is the same as 321*q, but we often leave out the multiplication sign. You could say q*321, but convention usually has the number come first then the variable second. The 321 is the coefficient.
