Explanation / Answer
The probability of winning either a large pizza or a soft drink= 0.10+0.02=0.12
The probability of not winning a prize is 1-(0.10+0.02)=0.88
The probability of not winning a prize on three consecutive visits to Tony's is 0.88^3=0.681
The probability of winning at least one prize on one of your next three visits to Tony's=1-0.681=0.319
