These would be independent events; therefore, we can multiply the probabilities of each of the two events.
Probability of flipping a head: 1/2
Probability of rolling an odd number with a single die: 1/6
Required probability : 1/2 x 1/6 = 1/12

The probability of flipping a quarter and getting heads is 1 in 2. the probability of rolling a die and getting 6 is 1 in 6.
It is 0.25
The best way to think about this is the following way: What is the probability of flipping heads once? 1/2 What is the probability of flipping heads twice? 1/4 (1/2 * 1/2) Using this we can derive the equation to find the probability of flipping heads any number of times. 1/2n Using this we plug in 25 for n and get 1/225 or as a decimal 2.98023224 x 10-8 or as odds 1:33,554,432
The probability of flipping Heads on a coin is 1 - a certainty - if the coin is flipped often enough. On a single toss of a fair coin the probability is 1/2.
The probability of flipping a coin 3 times and getting 3 heads is 1/2
