i) Getting 7 on the top when a dice is rolled  ii) Getting head on the top while tossing a coin 

Correct Answer - (i) 0.57 (ii) 0.43

Correct option is (B) equally likely When an unbiased coin is tossed then Probability of getting head is P(H) \(=\frac12\) and Probability of getting tail is P(T) \(=\frac12.\) Hence, getting a head when an unbiased coin is tossed...

Correct option is (C) 1/2 When a coin is tossed, possible outcomes are head and tail. S = {H, T} Total outcomes is n(S) = 2 Number of favourable outcomes of event of getting...

Correct option is (B) 1/2 Possible outcomes of experiment of tossing a coin are S = {H, T}. \(\therefore\) n (S) = 2 n (H) = 1, n (T) = 1 \(\therefore\) Probability of getting head on...

Correct option is (A) 1/6 Possible outcomes are S = {1, 2, 3, 4, 5, 6} \(\therefore\) n(S) = 6 Number which is a perfect square and a perfect cube is 1.    \((\because1^3=1\;\&\;1^2=1)\) Hence, favourable outcome...

Number of possible outcomes, n(S) = 2  Probability of getting a head, P(E’) = \(\frac{1}{2}\) = probability of getting a tail Since both probabilities are equal for both of the events, therefore both...
