Question

Find the probability of getting two heads if a coin is tossed thrice simultaneously?

Answer 1

If a coin is tossed thrice simultaneously :-

Sample space or  -

Total outcomes =

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

Favourable outcomes =

{ HHT, HTH, THH, HTH }

Probability = $\frac{Favourable }{total }$

                  = $\frac{4}{8}$

                  = $\frac{1}{2}$
