Problem 2E

The number of flaws in a given area of aluminum foil follows a Poisson distribution with a mean of 3 per $$\mathrm{m}^{2}$$. Let $$X$$ represent the number of flaws in a 1 $$\mathrm{m}^{2}$$ sample of foil.

a. P(X = 5)

b. P(X = 0)

c. P(X < 2)

d. P(X > 1)

e. $$\mu_{X}$$

f. $$\sigma_{X}$$

Step-by-Step Solution:

Solution

Step 1 of 7

Let X represents the no.of flaws in a sample

Here Xpoisson()

The pmf of Poisson distribution is p(x)=,x=0,1,2,............

Given mean =3

The mean of poisson distribution is

So =3
