A fair coin is tossed
(i) List the sample space.
(ii) What is p (head), the probability that a head will appear?
(iii) What is p (tail) ?

Explanation

(i) When a fair coin is tossed, there are two possible outcomes. Either head appears on the upper most face or tail appears on the upper most face.
`S={H,T},n(S)=2`
(ii) `" P(head)"=("No. of favourable outcomes")/("No. of possible outcomes")=(1)/(2)`
(iii) `" P(tail)"=("No. of favourable outcomes")/("No. of possible outcomes")=(1)/(2)`
