Detailed Solution

Concept: Probability of getting probability of the occurrence of an event isP(E)=Total number of favorable outcomesTotal number of outcomes.

Here, the sample space={TTT,TTH,THT,HTT,THH,HTH,HHT,HHH}

Let E is the event of getting two heads together.

Then, E={THH,HHT,HHH}

Thus, P(E)=n(E)n(S)=38.

Hence, the probability of getting two heads together when three coins are tossed simultaneously is 38.
