The experiment in which all possible outcomes are known but exact outcome can’t be predicted is called 

Correct option is (C) 6 Possible outcomes when a die is thrown are 1, 2, 3, 4, 5 and 6. \(\therefore\) Number of possible outcomes when a die is thrown is 6.

Correct option is (B) 2 When a coin is tossed there is only two outcomes are possible, either head occurs or tail occurs. Hence, total outcomes = 2

Correct option is (A) event The each outcome of a random experiment is called primary event.

Correct option is (C) 1 The sum of the probabilities of all outcomes of a random experiment is always 1.

Correct option is (A) 8 Three coins are tossed simultaneously then possible outcomes are S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}. \(\therefore\) The number of all possible outcomes is n(S)...

Correct option is (D) 6 When a dice is rolled, then possible outcomes are S = {1, 2, 3, 4, 5, 6}. Hence, total number of possible outcomes are 6.
