If you spin a dreidel twice:
1. how many outcomes are possible? What are they?
2. What is the probability of getting Nun both times?
p(Nun)*p(Nun)
3. How many outcomes contain Nun?
Nun first : 4 outcomes
Nun second: 4 outcomes
Nun both times: 1 outcome
4. What is the probability of getting Nun either time?
p(Nun first spin) + p(Nun second spin) - p(Nun both spins)
5. What is the probability of getting Nun and Gimel?
p(Nun)*p(Gimel) + p(Gimel)*p(Nun)
6. What is the probability of getting Nun or Gimel?
p(Nun or Gimel) : p(Nun) + p(Gimel) - p(Nun and Gimel)
If you spin the dreidel 3 times:

4. In how many outcomes are 2 of the spins the same?
5. In how many outcomes are all 3 spins different?
6. What is the probability of getting 3 Nuns in a row?
7. What is the probability of getting 2 Nuns and then a Gimel?
8. What is the probability of getting 2 Nuns and a Gimel in any order?
9. How many outcomes contain at least one Gimel?
10. What is the probability of getting at least one Gimel?
If you spin the dreidel 4 times:
1. How many outcomes are possible?
2. In how many outcomes are all 4 spins the same?
3. In how many outcomes are 3 of the spins the same?
