Probability Multiple Choice Questions
Probability Multiple Choice Questions 1) An event in the probability that will never be happened is called as - Unsure event Sure event Possible event Impossible event Answer: (d) Impossible event Explanation: An event that will never be happened is known as the impossible event. For example - Tossing double-headed coins and getting tails in an impossible event, rolling a die and getting number > 10 in an impossible outcome, etc. 2) What will be the value of P(not E) if P(E) = 0.07? 90 007 93 72 Answer: (c) 0.93 Explanation: If the probability of happening of an event P(E) and that of not happening is P(E), then P(E) + P(not E) = 1 So, P(not E) = 1 - P(E) Since P(E) = 0.07 P(not E) = 1 - 0.07 P(not E) = 0.93 3) What will be the probability of getting odd numbers if a dice is thrown? 1/2 2 4/2 5/2 Answer: (a) 1/2 Explanation: The sample space when a dice is rolled, S = (1, 2, 3, 4, 5, and 6) So, n (S) = 6 E is the event of getting an odd number. So, n (E) = 3 Probabi...
