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 maximum distance (in nautical miles) that a radio transmitter signal can be sent is represented by the expression 1.23h√, where h is the height (in feet) above the transmitter. estimate the maximum distance x (in nautical miles) between the plane that is receiving the signal and the transmitter. round your answer to the nearest tenth.
