Question
If three coins are flipped, find the probability that exactly two heads turn up.
Step 1
Each coin has two possible outcomes: heads (H) or tails (T). Therefore, for three coins, the total number of possible outcomes is $2^3 = 8$. These outcomes are: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. Show more…
