Jennifer flipped a coin three times and got heads each time. What is the probability that she gets heads on the next flips?

Question: Jennifer flipped a coin three times and got heads each time. What is the probability that she gets heads on the next flips?

Solution:
Each coin flip is an independent event. This means that the outcome of previous flips has no effect on the outcome of future flips.

A fair coin has only two possible outcomes:
Heads (H)
Tails (T)

The probability of getting heads in any single flip is:
P(Heads) = Number of favorable outcomes/Total number of possible outcomes
∴ P(Heads) = 1/2

Even though Jennifer got heads three times in a row, the probability for the next flip remains exactly the same.

∴ The probability that she gets heads on the next flip is 1/2.
