Hello,

My first question is urgent

1-)Investigate a lottery competition somewhere in the world. Explain how the lottery works, and what needs to happen for someone to win the jackpot, and at least one of the minor prizes.

a-) Calculate the probability of winning each of the prizes you described, giving a full explanation of your work.

b-) Consider the cost of playing. Do you think the prizes offered are fair? If not, why not, and why do you think people continue to play?

2-)There are 8 parents and 43 students going on a school trip. Two groups are made, a large one with thirty students and five parents, and a small group with 13 students and three parents.

a-)How many different ways can be the parents be chosen for the small group?

b-)How many ways can the students be chosen for the large group if Stefan and Dylan must be in the small group?

c-)How many ways can the groups be arranged if Reena and both her parents must be in the small group?
