Three coins are tossed together. The probability of getting exactly two heads is
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → \(\displaystyle\frac{3}{8}\)
Each coin shows H or T, so there are \(2 \times 2 \times 2 = 8\) equally likely outcomes:
HHH, HHT, HTH, THH, HTT, THT, TTH, TTT
The outcomes with exactly two heads are HHT, HTH and THH, which is 3 outcomes.
\( \displaystyle P(\text{exactly two heads}) = \frac{3}{8} \)
