Medium
Two coins are tossed simultaneously. What is the probability of getting exactly one head?
Explanation
Explanation
The sample space for two coins is {HH, HT, TH, TT} — 4 equally likely outcomes. Exactly one head occurs in 2 of them (HT, TH). So P(exactly one head) = 2/4 = 1/2.
PRO TIP
Re-check your working by substituting the answer back into the original question.
