Question

If a coin is tossed200times. Find the probability of getting a head 100times

Answer 1

n(S) = 400

n(E) = 200

P(E) = n(E)/n(S)

= 200/400

=1/2

I hope this is correct

Answer 2

p[e]= no. of favourable outcomes/total no. of possible outcomes

    then,  

           p[e]= 200 /400   =1/2
