Acommunity college has 150 word processors. the probability that any one of them will require repair on a given day is 0.025. to find the probability that exactly 25 of the word processors will require repair, one will use what type of probability distribution? a) normal distributionb) poisson distributionc) binomial distributiond) none of these choices

Step-by-step explanation:

A binomial distribution uses discrete variables, which represents whole numbers, like persons. Also, this type of distribution is used when only to events are possible: success or failure. In this case, success would be require repair, and failure not require repair.

Binomial distribution is also characterised by having a fixed probability k about the success occurrence between trials, which is 0.025 in this case.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
