The probability of rolling a 2 on a die before flipping a heads on a coin is 1 in 12.

The probability of rolling a 2 is 1 in 6. The probability of flipping heads is 1 in 2. Since these are sequentially unrelated events, you simply multiply the probabilities together.

What is the probability of rolling a 1 or 6 on a number cube and flipping tails on a coin?

The probability of flipping tails on a perfect coin in a perfect toss is 0.5. The probability of rolling 1 on a die is 1 in 6. Likewise, the probability of rolling 6 on a die is 1 in 6. So the probability of rolling either 1 or 6 is 2 in 6 (which is 1 in 3).

How do you figure out the probability of 2 separate events For instance what is the probability of flipping a coin to heads and rolling a 5 on a dice?

You take the probability of each event and multiply them. In the case of the given example, your odds or flipping a head and rolling a 5 would be 1/2 * 1/6, which equals 1/12.


What is the probability of flipping heads and rolling an odd number?

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


What is the probability of rolling 3 on a dice and flipping a coin to heads?

What is the probability of getting heads when flipping a coin and getting a number greater than or equal to 4 when rolling a die?

It is 0.25


What are complementary events in probability?

Complementary events are events that are the complete opposite. The compliment of event A is everything that is not event A. For example, the complementary event of flipping heads on a coin would be flipping tails. The complementary event of rolling a 1 or a 2 on a six-sided die would be rolling a 3, 4, 5, or 6. (The probability of A compliment is equal to 1 minus the probability of A.)


What is used to determine the probability of two indepepdent events occurring?

Multiply together the probability that each event would have of occurring by itself. For example, the probability of rolling a "3" on a single die is 1/6 ,because there are 6 different possibilities. And the probability of flipping a "heads" on a coin is 1/2 , because there are two possibilities. Then the probability of rolling a "3" AND flipping a "heads" is ; 1/6 x 1/2 = 1/12 .


What is the probability of flipping a coin and getting tails and than rolling a number greater than two on a number cube?

The probability of getting tails on a coin is SMALLER than rolling a number greater than 2
