Answer:
3/8
Explanation:
Three coins are tossed simultaneously.
Possible outcomes ={HHH,HHT,HTH,HTT,TTT,TTH,THT,THH}
No. of total outcomes =8
Favourable outcomes ={HHT,HTH,THH}
No. of favourable outcomes =3
Therefore,
Probability of getting exactly two heads =
No. of total outcomes/No. of favourable outcomes
=
8/3
Hence the probability of getting exactly two heads is = 8/3
