Statistics

1. We throw a dice for 6 times and we get as a result numbers:

1 2 3 4 5 6

Calculate variance . use n-1 instead of n.

2. the variance of throwing a dice, if sample is not closed?

when we can throw a dice as many times as possible and make an overall assumption about all dices.

3. throwing a dice, probability for all numbers is 16. What is the expected value of throwing a dice?

4. Let assume that we throw a coin and we win if we get heads and we lose if get tails. If we get tails, we lose 10 euros and if we get heads, we win 11 euros. What is the expected amount that we get?
