The number of defective components produced by a certain process in one day has a Poisson distribution with a mean of 20. Each defective component has probability 0.60 of being repairable.
a) Find the probability that exactly 15 defective components are produced in a particular day. Round your answer to four decimal places.

The probability that exactly 15 defective components are produced in a particular day is 0.0516

Step-by-step explanation:

Probability function :

We are given that The number of defective components produced by a certain process in one day has a Poisson distribution with a mean of 20.

So,

we are supposed to find the probability that exactly 15 defective components are produced in a particular day

So,x = 15

Substitute the values in the formula :

Hence the probability that exactly 15 defective components are produced in a particular day is 0.0516

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

    200 words per minute

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
