Suppose a binomial event has a probability of success of 0.3, and 1250 trials are performed. what is the standard deviation of the possible outcomes? round your answer to two decimal places.

16.20

Step-by-step explanation:

For any binomial event , the formula to calculate the standard deviation of the possible outcomes is given by :-

Given: The probability of success p = 0.3

Then , the probability of failure q= 1-0.3=0.7

Now,  by using above formula , the standard deviation of the possible outcomes will be :-

Hence, the standard deviation of the possible outcomes = 16.20

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
