View Hints \\(Probability = \\frac{Number \\ of \\ favorable \\ outcomes }{Total \\ number \\ of \\ outcomes}\\) The probability of an impossible event is 0 and the probability of a certain event is 1. Probability is the ratio of favorable outcomes to the total number of outcomes. The probability of an impossible event is 0 and the probability of a certain event is 1. Find probability of occurence of head first \\(P = \\frac{favourable}{total}\\) P(E) + P(not E) = 1 ∴ 0.05 + P(not E) = 1 ⇒ P(not E) = 1 – 0.05 = 0.95 Thus, probability of 'not E' = 0.95. The event that is certain to happen or cannot happen at all are not included in probabilistic events. Can we recall how many kings are there in a deck of 52 cards? There should be only two heads. |
