Short Answer TypeIf we toss a pair of coins twice then we get following possible outcomes (S).
i.e., S = { HT, TH, HH, TT }
⇒ n(S) = 04
Let E be the favourable outcomes of getting one head, then
E = { HT, TH }
⇒ n(E) = 2
Therefore, P(E) = 
Let F is the favourable outcomes of getting two tails, then
F = { T, T }
⇒ n(F) = 1
Therefore, P(F) = 
Two coins are tossed simultaneously. Find the probability of getting.
(i) two heads, (ii) at least one head, (iii) no head.
A die is thrown once. Find the probability of getting
(i) an even number.
(ii) a number greater than 3.
(iii) a number between 3 and 6.
