The probability of rolling a number greater than 1 is 5/6.
2/6=1/3
mean = 5, variance = 5
Usually, it takes 2-5 flips until a head appears.
Each toss has 2 outcomes; so the number of outcomes for 3 tosses is 2*2*2 = 8
9
Outcomes are 2 X 6 = 12.
There is only one even number over 4, which is 6, so when rolling the number cube, the chances of it coming up are 1/6.
1/6
There are 36 possible outcomes of which 6 show the same number on each, so the odds are 5 - 1 against.
The answer will depend on what is being tossed!
The number of combinations - not to be confused with the number of permutations - is 2*21 = 42.
