In: Statistics and Probability
The probability of winning a raffle with a single ticket is 1 in 400,000,000. In May and June, 200,000,000 tickets were bought for the raffle.
1. Assume the tickets win or lose independently of each other and give the exact probability that there was no winner during the two months.
2. Only using a basic scientific calculator, give an approximation to the same question from part 1. Explain why this approximation is a good one.
Explain your work please.
