2.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
a) Calculate P(Win or Draw)
b) Calculate P(Lose)

Answer 1

Answer:

1. probability of green marble= 25

probability of red marbles= 10

favourable outcomes= 25+10

total outcomes = 25+10+9+6

favourable outcomes= 35

total outcomes= 50

probability= 35/50

= 7/10
