Suppose you participate in a chess tournament in which you play n games. In each game, you are equally likely to win, lose, or t
ie, and the outcome of each game is independent of the outcome of every other game. You collect 2 points for each win, 1 point for each tie, and 0 points for each loss. Let Y be the total number of points earned over the n games. Find E[Y ] and Var[Y ].
What is 32% of 75?
Y is 32% of 75.
Equation: Y = P% * X.
Solving our equation for Y:
Y = P% * X.
Y = 32% * 75.
Converting percent to decimal:
p = 32%/100 = 0.32.
Y = 0.32 * 75 .
Y = 24.
Answer is 24.
