Meg flipped a penny 2 times. What is the probability she get 2 heads?

what is (1/2)(1/2) ?

To calculate the probability of two independent events occurring, we can use the multiplication rule. The probability of one event, in this case, getting a head (H), is 1/2 since there are two possible outcomes, heads or tails, and they have equal chances of occurring.

Since Meg flips the penny twice, we need to find the probability of getting a head in both flips. We multiply the individual probabilities together to get the joint probability.

Probability of getting a head on the first flip (H): 1/2
Probability of getting a head on the second flip (H): 1/2

Using the multiplication rule: Probability of getting 2 heads = Probability of H on the first flip x Probability of H on the second flip

Probability of getting 2 heads = (1/2) x (1/2)
Probability of getting 2 heads = 1/4

Therefore, the probability that Meg gets 2 heads when flipping the penny twice is 1/4 or 25%.
