Multiple choice

If $3$ coins are tossed simultaneously, the probability of $1$ head and $2$ tails is:

  1. $\dfrac{1}{8}$
  2. $\dfrac{3}{8}$
  3. $\dfrac{5}{8}$
  4. $\dfrac{7}{8}$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Total outcomes for 3 coins = 2^3 = 8. Outcomes with 1 head and 2 tails are (HTT, THT, TTH), which is 3 outcomes. Probability = 3/8.

AI explanation

When 3 coins are tossed, the total number of possible outcomes is 2 cubed, which is 8. The favourable outcomes for getting exactly 1 head and 2 tails are HTT, THT and TTH, giving 3 favourable outcomes. Using the classical probability formula, the probability is 3 divided by 8. The result is 3/8.
