Answer:

B.

Step-by-step explanation:

That would be B.

8/3 + √(-7/3) :-  because it consists of a real part ( the 8/3) and an imaginary part √(-7/3).

The √(-7/3) is usually written as √(7/3)i where i is √-1, so the complex number is 8/3 + √(7/3)i.

In a batch of​ 8,000 clock radios 7​% are defective. A sample of 1313 clock radios is randomly selected without replacement from
PIT_PIT [208]

Answer: Probability that the entire batch will be rejected is 0.611.

Step-by-step explanation:

Since we have given that

Number of clock radios in a batch = 8000

Probability of defective clock radio = 7%

According to question, we have mentioned that A sample of 13 clock radios is randomly selected without replacement from the​ 8,000 and tested.

We will use "Binomial distribution":

here, n = 13 and

p (probability of success) = 7% = 0.07

so, we need to find that

P(the entire batch will be rejected)  = P(at least one of those test is defected)

So, it becomes,

P(at least one of those tested is defective) = 1 - P(none are defective)

So, P(none are defective ) is given by

(1-0.07)^{13}\\\\=0.93^{13}\\\\=0.389

So, P(at least one of those tested is defective) = 1 - P(none are defective)

                                                                             =  1 -  0.389

                                                                             =  0.611

Hence, Probability that the entire batch will be rejected is 0.611.
