Suppose the number X of tornadoes observed in a particular region during a 1-year period has a Poisson distribution with λ = 9. (a) Compute P(X<=5).
(b) Compute P(6<= X<= 9)
(c) Compute P(10<= X)
(d) What is the probability that the observed number of tornadoes exceeds the expected number by more than 1 standard deviation?

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

3

step-by-step explanation:

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
