Answer: 4
Step-by-step explanation:
For any binomial variable X having parameters n (total number of trials ) and p (probability of getting success in each event), the standard deviation is given by :-

As per given , we have
n= 100 , p= 20%=0.20
Then, the standard deviation of this binomial distribution is :

Hence, the standard deviation of this binomial distribution is <u>4</u>.
Answer:
(x - .20)(x - .50)
= (.20)(.50)
= 0.1
x = 
x = .32
the product of two numbers decrease by 32%
