2 coins are tossed. Find the probability of getting 1 head and 1 tail

We can either flip HT or TH. Let's review probabilities:

• HT = 1/2 * 1/2 = 1/4 <-- We multiply since each event is independent
• TH = 1/2 * 1/2 = 1/4 <-- We multiply since each event is independent

P(1 H, 1 T) = P(HT) + P(TH)
P(1 H, 1 T) = 1/4 + 1/4
P(1 H, 1 T) = 2/4

Using our fraction simplifier, we can reduce 2/4 to 1/2
P(1 H, 1 T) = 1/2
