1 3.5 Probabilities Using Combinations

2 Scratch Tickets What is your probability of winning grand prize? Numbers are 1-25 5 are picked Order of picking not important

3 Scratch Tickets What is your probability of winning second prize? (4 out of 5 numbers to win) Numbers are 1-25 5 are picked Order of picking not important

4 Task Force A university task force of 8 people is to be formed from 16 members of the student government and 10 professors. Each person is equally likely to be chosen What is probability that there is an equal amount of students and profs? What is the probability that at least six members are students?
