Question

The probability that an electronic

device produced by a company does

not function properly is equal to 0.1.

If 10 devices are bought, then the

probability, to the nearest thousandth,​

Answer 1

Answer:

Let q be the probability a device does not function properly and p=1−q=0.9, the probability that a device functions properly.

Step-by-step explanation:

Since there are only two possible results it is a binomial distribution.

C(10,7)×0.9

7

×0.1

3

where C(10,7) is the number of ways that 7 items are selected from 10 and is given by,

P=C(10,7)=

7!3!

10!

=0.057

Hence, option A is correct.
