Let {mi(t), t > =0}, i=1,2,3 be independent poisson processes with respective rates λi, i=1,2, and set: n1(t)=m1(t)+m2(t), n2(t)= m2(t)+m3(t)the stochastic process {(n1(t), n2( t> =0} is called a bivariate poisson processa) find p{n1(t)=n, n2(t)=m}b) find cov(n1(t), n2(t)}

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms
