Question

Find the probability of head coming up when a coin is tossed once time?

Answer 1

Sample Space = [H,T] = 2

P(of getting a head) P(H) = $\frac{no. of observations}{sample space}$

                                         

                                           =$\frac{1}{2}$

                                       

                                            = 0.5

Answer 2

Head and tail (H, T) be the space is equal to 2

p is getting a head p(H)=no. of observations by spaces =1/2

Therefore,0.5
