Question

If a binomial event has a probability of success of 0.2, how many successes would you expect out of 6000 trials?

Answer 1

0.2 is 1/5 so 1/5 of 6000 is 1,200 successes

Answer 2

The success would expect are 1200.

Explanation:

Given : If a binomial event has a probability of success of 0.2.

To find : How many successes would you expect out of 6000 trials?

Solution :

The probability of success p=0.2.

The number of trials is n=6000

The formula to find number of successes is

The mean (expected value) of number of successes is the multiple of success and number of trials,

`M=np`

`M=6000* 0.2`

`M=1200`

Therefore, The success would expect are 1200.
