Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:

Answer:
4066+2/3
Step-by-step explanation:
So to find the surface area of the bottom box it will be :
2((20+40)x15+20x40)=3400
For the Half cylinder on to it will be:
10x10xpiex40x1/6= 2000/3pie
Your answer is .062 because:
.85 can't go into .05
so you see how many times it can go into .052 but it can't
so then you go to see how many times it can go into .0527
.85 times 62 is .0527
that means .85 can go into .057 62 times
