Three coins are tossed once. find the probability of getting 3 tails​

Answer» SAMPLE space of the above experiment would be :

{TTT, TTH, THT, HTT, THH, HTH, HHT, HHH}

Hence, total number of FAVOURABLE outcomes = 8

Event is "getting 3 TAILS"

The only favourable outcome is {TTT}

Hence, number if favourable outcomes = 1

Thus,

Probability = total outcomes/favourable outcomes

= 1/8
