I have three question about my data homework can anyone please help?

1) If you repeatedly cut a deck of cards, what is the probability that you will cut an ace in fewer than five cuts? 2) It is estimated that the probability of winning in blackjack is 0.46 if you are given corresponding odds in favor of winning what must you wager to win $15.00? 3) In a manufacturing process, it is estimated that only 2 % of the bolts that are machined are declared defective, that is they are either too large or too small. In a package of 50 bolts what is the probability that there is at least one defective bolt?
