New Question:

Nathan knows that his probability of kicking more than four goals on a wet day is 0.3, while on a dry day it is 0.6. The probability that it will be wet on the day of the next game is 0.7. Calculate the probability that Nathan will kick more than four goals in the next game.

A spinner is numbered from 0 to 5, and each of the six numbers has an equal chance of coming up. A player who bets $1 on any numbers wins $5 if that number comes up, otherwise the $1 is lost. What is the player's expected propit on the game?

X=+$4, Pr = 1/6
X=-$1, Pr = 5/6

E(x) = 4/6 - 5/6 = -1/3
