i only accept correctly and well explained answers!

We asked 6 students how many times they rebooted their computers last week.

There were 4 Mac users and 2 PC users.

The PC users rebooted 2 and 3 times.

The Mac users rebooted 1, 2, 2 and 8 times.

Let C be a Bernoulli random variable representing the type of computer of a randomly chosen student (Mac = 0, PC = 1).

Let R be the number of times a randomly chosen student rebooted (so R takes values 1,2,3,8).

(a) Create joint probability table for C and R. Be sure to include the marginal probability mass functions.

(b) Compute E(C) and E(R).

(c) Determine the covariance of C and R and explain its significance for how C and R are related. (A one sentence explanation is all that's called for.)

Are R and C independent?

(d) Independently choose a random Mac user and a random PC user.

Let M be the number of reboots for the Mac user and W the number of reboots for the PC user.

(i) Create table of the joint probability distribution of M and W, including the marginal probability mass functions.

(ii) Calculate P(W > M).

(iii) What is the correlation between W and M?

analyze, illustrate ,explain and provide examples for these questions

case study;Some people think that humans' development of technology has enabled us to short-circuit evolution, or step outside of evolution. But evolution is not some magical transformation that happens in the wild to dim-witted creatures, propelling them ever towards greater complexity. Evolution is just the observation that creatures change over time because varieties that do best at surviving and reproducing in a given environment are more able to pass their genetic traits on to the next generation. Technology is part of evolution, as is poetry and economics, in so far as they affect survival and reproduction, and can be passed on genetically. Those races that use technology in order to better survive and reproduce are able to pass along their technology-minded genes to the next generation.
