A coin is tossed thrice. The probability that exactly two heads show up is
-
-
1 8 -
2 8 -
3 8 -
4 8
-
Correct Option: C
As we know that A coin has two faces head and tail.
Total (Exhaustive) number of cases = 2³ = 8
Possible outcomes = (HHH, HHT, HTH, THH, HTT, TTH, THT, TTT)
Favourable number of cases = 3
| ∴ Required probability = | |
| Total (Exhaustive) number of cases |
| Required probability = | |
| 8 |
