If you flip three fair coins, what is the probability that you'll get all three tails?
Probability defines the likelihood of occurrence of an event.
Answer: The probability of getting three tails on flipping three fair coins is 1/8
Let's look into all the possible outcomes of tossing three fair coins
We know that,
Probability of an event (E) = Number of favorable outcomes / Total number of outcomes
Let, H = Heads, T = Tails
(H,H,H), (H,H,T), (H,T,H), (H,T,T), (T,H,H), (T,H,T), (T,T,H), (T,T,T)
Total number of outcomes = 8
Number of outcomes that gives three tails = 1
Thus, number of favorable outcomes = 1
Probability of getting three tails = Number of favorable outcomes / Total number of outcomes
