Answer:
Step-by-step explanation:
Given that a grocery supplier believes that the mean number of broken eggs per dozen is 0.8 with a standard deviation of 0.6.
Here we assume the cartons of eggs are independent
a) Mean value of eggs in 8 dozens = 8 Expected value in 1 dozen
b) Var (8x) (Here 8 dozens)
(assuming independent)
Otherwise we have Var(x1+x2+x3+...)=sum of var of xis + cov (xi,xj)
Thus we have to assume independent to avoid covariance
So Var(8x)=64 Var(x)
STd dev for 8 dozens = 8(0,6) = 4.8
c) To avoid covariance i.e. variance among pairs of dozens we assume independence.

Answer:
99.96%
Step-by-step explanation:
Given the information:
=> the are 25 people in total
Hence, the total possible outcomes of all the members in the 4 committee:
They want us to find the probability that the committee will consist of at least one student, which means that
=(Total possible outcome - committee with no student) / Total possible outcomes
So we need to find the possible outcomes of committee with no student:
= 
=> the probability that the committee will consist of at least one student.
= (12650 - 5) / 12650
= 0.9996
= 99.96%
Hope it will find you well.
V=(pi)r 2 h. ( volume is equal to pi times radius squared times height). V= pi 2^2 x8
Pi times 4times8= pi times 32. Put in a calculator pi times 32 and you get 100.5 cubic inches ( I haven’t done this in awhile but I think this is correct)
