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

step-by-step explanation:

250-112 = 138

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
