Answer:
When we toss three coins simultaneously then the possible of outcomes are:
HHH or HHT or HTH or THH or HTT or THT or TTH or TTT respectively;
Where H is denoted for head and T is denoted for tail.
Therefore, total numbers of outcome are 2^3 =8
Exactly two heads
Favourable cases ={HHT,HTH,THH}
Probability of getting exactly two heads = 3/8
