The result of a game is Win, Lose or Draw. After 80 games
relative frequency of the result Win is 0.4
relative frequency of the result Lose is 0.25
How many of the games had the result Draw?

Total Probability must be 1

1 - (.4 + .25) = .35

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
