Question 14

A bio-scientist is working on the analysis of the cancer cells. To identify whether the cell is cancerous or not, there has been hundreds of tests are done with small variations to say yes to the problem. Given the test result for a sample of healthy and cancerous cells, which of the following technique you will use to determine whether a cell is healthy?

Question 15

Suppose you have been given two Random Variables X and Y, whose joint distribution is already known, the marginal distribution of X is simply the probability distribution of X averaging over information about Y. It is the probability distribution of X when the value of Y is not known. So how do you calculate the marginal distribution of X

Options:

A.

This is typically calculated by summing the joint probability distribution over Y.

B.

This is typically calculated by integrating the joint probability distribution over Y

C.

This is typically calculated by summing (In case of discrete variable) the joint probability distribution over Y

D.

This is typically calculated by integrating(ln case of continuous variable) the joint probability distribution over Y.

Question 16
