Suppose a binomial event has a probability of success of 0.3, and 750 trials are performed. what is the standard deviation of the possible outcomes? round your answer to two decimal places.
a. 16.20
b. 12.55
c. 8.22
d. 10.61

B.12.55

Step-by-step explanation:

Given: In a binomial event , the probability of success = 0.3

i.e. p =0.3

Then, q=1-P=1-03=0.7

The total number of trial performed n= 750

Now, the standard deviation of the proportion is given by :-

Hence, the standard deviation of the possible outcomes = 12.55

true

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
