Answer:
Variance for a total of 150 games is 20.67
Step-by-step explanation:
If x follows binomial distribution with parameters n and p then the probability distribution of tends to N (0.1)
As where E(x)= np, var (x) = npq
var (x) = 1500.165 (1-0.165)
(since, n= 150, p=0.165,
q = 1-p = 1-0.165)
= 20.66625
var (x) = 20.67
variance for a total of 150 games is 20.67
The correct way to write that is 309,058,304.
It helps if you say it out loud to yourself. that is what helped me! ☺
Hope this helps
6 divided by -0.5 is -12. So that means you could multiply -0.5 and -12 to get 6. Hope this helps!
