Explanation / Answer

Solution:-

1) The probability that a winning team scored less than 3 goals is 0.5191.

Number of team scoring less than 3 goals = 29 + 39 = 68

Total number of goals = 131

The probability that a winning team scored less than 3 goals = 68/131.

2) The probability that selected bag is of potato chips = 0.46875

Number of potato chips bags = 15

Total number of bags = 32

The probability that selected bag is of potato chips = 15/32 = 0.46875
