a robot fires shots at a moving target. for the first shot, the probability of hitting the moving target is . for subsequent shots beyond the first shot, the probability of hitting the moving target is if the previous shot is a hit (for example, the probability of hitting the moving target on the 3rd shot is if the 2nd shot is a hit) and the probability of hitting the moving target is if the previous shot is a miss. what is the mean and variance of the number of hits? mean (rounded to the nearest whole number): variance (correct to 2 decimals
