If you flip three fair coins, what is the probability that you'll get a head on the first flip, a tail on the second flip, and another head on the third flip?
Q. If you flip three fair coins, what is the probability that you'll get a head on the first flip, a tail on the second flip, and another head on the third flip?
Coin outcomes: Each coin has 2 possible outcomes, heads (H) or tails (T).
First flip probability: The probability of getting heads on the first flip is 21.
Second flip probability: The probability of getting tails on the second flip is also 21.
Third flip probability: The probability of getting heads on the third flip is again 21.
Combined probability calculation: To find the combined probability of independent events, we multiply their probabilities: (21)×(21)×(21).
Combined probability result: Calculating the combined probability: 21×21×21=81.
