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

the mean and mad

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
