Answer:
The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.
Answer:
35280ways
Step-by-step explanation:
let X be the number of ways the letters can be arranged with no restriction,
let M be the number of ways they can be arranged if the letters C and O must stand together,
and let the number of ways the letters C and O can be arranged if they can not stand together.
X=8!
M= 7!
N=X–M=8!–7!=35280 ways
