Solution

The correct option is D

1/4


When three coins are tossed simultaneously, there are 8 possible outcomes, which are (HHH), (HHT), (HTH), (THH), (HTT), (THT), (TTH), (TTT), where H is represents the head and T represents the tail.
Favourable outcomes of getting all heads or all tails are HHH and TTT.
We know that, Probability of an event E, P(E) =Number of favourable outcomesTotal number of outcomes
Hence, the required probability = 28 = 14
