Question

Michelle estimates that the probability that her Hockey team will win their next game is 0.2, and the probability they will draw is 0.5. Calculate P(Win or draw). Calculate P(Lose)

Answer 1

P(win) = 0.2

P(draw) = 0.5

P(win or draw) = 0.5 + 0.2 = 0.7

P(lose) = 1 - 0.7 = 0.3

Hope this helps you :)

Answer 2

p(loss)=1-(0.5+0.2)

=0.3
