Explanation

Total outcomes for 4 coins = 2^4 = 16. Favorable outcomes for 2 heads and 2 tails = 4C2 = 6. Probability = 6/16 = 3/8.

AI explanation

When four coins are tossed, the total number of possible outcomes is 2^4 = 16. The number of ways to get exactly two heads is given by the combinations formula 4C2, which equals 6. The probability is the ratio of favorable outcomes to total outcomes, 6/16, which simplifies to 3/8.
