GIVEN: Three coins are tossed simultaneously.

When three coins are tossed then the possible outcome will be:  

TTT, THT, TTH, THH. HTT, HHT, HTH, HHH.

Total number of  outcomes =  8.

(i) Let E1 = Event of getting exactly two heads  

Then the outcome variable to E1 is THH, HHT ,HTH.

Number of outcomes favourable to E1 = 3

Probability (E1) = Number of favourable outcomes / Total number of outcomes

P(E1) = ⅜  

Hence, probability of getting exactly two head ,P(E1)  = ⅜ .  

\boxed{Hope    it     helps}
