The following histogram shows the theoretical probability of the number of heads you might get after flipping for coins simultaneously. If you were to flip four coins what is the probability that you get a two or more coins that land heads up?

Use binomial probability since there are only two possibilities: success and failure, where success represents getting a heads, and tails being a fail. Therefore we are trying to find P(X=2), which is (42)⋅(0.5)2⋅(0.5)2=0.375.

The probability that you get two or more coins that land heads up is 0.6875.

What is the theoretical probability?

Theoretical probability is an approach in probability theory that is used to calculate the probability of an outcome of a specific event.

The following histogram shows the theoretical probability of the number of heads you might get after flipping for coins simultaneously.

If you were to flip four coins what is the probability that you get two or more coins that land heads up is;

Probability = flip 0 coin + flip 1 coin + flip 2 coin

Probability = 0.375 + 0.25 + 0.0625

Probability = 0.6875

Hence, the probability that you get two or more coins that land heads up is 0.6875.
