WebbSome of the examples of the mutually exclusive events are: When tossing a coin, the event of getting head and tail are mutually exclusive events. Because the probability of getting head and tail simultaneously is 0. In a six-sided die, the events “2” and “5” are mutually exclusive events. We cannot get both events 2 and 5 at the same ... WebbLet's take a look at a few examples of probability. Example 1- Probability Using a Die Given a standard die, determine the probability for the following events when rolling the die …
WebbExample : Find the probability of getting a head in a toss of an unbiased coin. Solution : The sample space associated with the random experiment is S = {H, T}. ∴ Total number … WebbThe probability of E occurring will be- P (E) = 28 52 = 7 13 P (E) = 28 52 = 7 13 ∴ ∴ The probability of the card either being red or a king card is 7 13 7 13 Example 2 A juggler has seven red, five green, and four blue balls. During his stunt, he accidentally drops a ball and doesn't pick it up. As he continues, another ball falls down.
