Four club vans carrying 150 cricket players from the club and arrive at a cricket ground. The van carry 26, 34, 40, and 50 players, respectively. Among these players, single player is chosen randomly. Let A represents the number of players that were on the vans carrying the randomly selected players. Find the E[A] Var(4).
