An unbiased die is thrown twice. Let the event A be,Even number on the first throw and B the event, Even number on the second throw. Check the independence of the events A and B

Let, X denote the number of colleges where you will apply after your results and P (X = x) denotes your probability of getting admission in x number of colleges. It is given that P(X=x)={k x,ifx=0or1 2k x,ifx=2k(5-x),ifx=3or4 0,ifx >4 where k is a positive constant. Find the value of k . Also find the probability that you will get admission in (i) exactly one college (ii) at most 2 colleges (iii) at least 2 colleges.

An unbiased die thrown twice. Let the event A be 'even number on the first throw' and B the event 'even no. on the second throw'. Check the independence of the events A and B.

Let X = time (in minutes) that elapses between the bell and the end of the lecture in case of a college professor. If X has p.d.f. f(x)={{:(kx^(2)","0lexle2),(0", otherwise"):} , then k =
