What is the probability of three coins falling all heads up when tossed simultaneously?

  1. $\dfrac{1}{2}$
  2. $\dfrac{1}{6}$

  4. $\dfrac{7}{8}$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Each coin has 2 outcomes. For 3 coins, total outcomes = 2^3 = 8. Only one outcome (H, H, H) is all heads. Probability = 1/8.

AI explanation

When three coins are tossed, the total number of possible outcomes is 2 cubed, which equals 8. Only one of these outcomes results in all heads. The probability is 1 favorable outcome divided by 8 possible outcomes, giving 1 over 8.
