Answer 2

The number of values of binomial distribution = 1340

Given :

Mean of binomial probability distribution is 857.6 and probability is 64%

To find :

The number of values of binomial distribution

A. 1040

B. 1340

C. 1240

D. 1140

Solution :

Step 1 of 2 :

Form the equation

Let number of values of binomial distribution = n

The mean of binomial distribution = μ = 857.6

Probability = p = 64% = 64/100 = 0.64

Now we know that

μ = np

⇒ 857.6 = n × 0.64

Step 2 of 2 :

Find number of values of binomial distribution

$\displaystyle \sf{ \implies 857.6 = n \times 0.64}$

$\displaystyle \sf{ \implies n = \frac{857.6}{0.64} }$

$\displaystyle \sf{ \implies n = 1340 }$

The number of values of binomial distribution = 1340

Hence the correct option is 1340

Correct Question : Mean of binomial probability distribution is 857.6 and probability is 64% then number of values of binomial distribulion1040. 1340. 1240. 1140
