If they are fair coins, it is 1/16.

The sample space for tossing 2 coins is (H = Heads & T = Tails): HH, HT, TH, TT

the probability is 0.03125 or 3.123%

It is 3/4 or 0.75

The probability of tossing 6 heads in 6 dice is 1 in 26, or 1 in 64, or 0.015625. THe probability of doing that at least once in six trials, then, is 6 in 26, or 6 in 64, or 3 in 32, or 0.09375.

1/2 * 1/6 = 1/12
