Consider a random variable X with the following probability mass function P(X=0)=0.25, P(X=5)=0.5, P(X=12)=0.25. What is the expected value (or mean) of X?
6)Acertain player say X, is known to win with probability 0.3 if thetrack is fast and 0. 4 if the track is slow. For Monday there is a 0.7probability ofa fast track and 0.3 probability of a slow track. What isthe probability that player X will win on Monday.
