Example 1: A coin is thrown 3 times .what is the probability that atleast one head is obtained? Example 2: Find the probability of getting a numbered card when a card is drawn from the pack of 52 cards. Example 3: There are 5 green 7 red balls. Two balls are selected one by one without replacement. Find the probability that first is green and second is red. Example 4: What is the probability of getting a sum of 7 when two dice are thrown? Example 5: 1 card is drawn at random from the pack of 52 cards. Example 6: Two cards are drawn from the pack of 52 cards. Find the probability that both are diamonds or both are kings. Example 7: Three dice are rolled together. What is the probability as getting at least one '4'? Example 8: A problem is given to three persons P, Q, R
whose respective chances of solving it are 2/7, 4/7, 4/9 respectively. What is the probability that the problem is solved? Probability of problem getting solved = 1 – (5/7) x (3/7) x (5/9) = (122/147) Example 9: Find the probability of getting two
heads when five coins are tossed. Example 10: What is the probability of getting a sum of 22 or more when four dice are thrown? Example 11: Two dice are thrown together. What is the probability that the number obtained on one of the dice is multiple of number obtained on the other dice? Example 12: From a pack of cards, three cards are drawn at random. Find the probability that each card is from different suit. Example
13: Find the probability that a leap year has 52 Sundays. Example 14: Fifteen people sit around a circular table. What are odds against two particular people sitting together? Example
15: Three bags contain 3 red, 7 black; 8 red, 2 black, and 4 red & 6 black balls respectively. 1 of the bags is selected at random and a ball is drawn from it. If the ball drawn is red, find the probability that it is drawn from the third bag. What are some examples of probability questions?If two coins are tossed simultaneously, what is the probability of getting exactly two heads? From a well-shuffled deck of 52 cards, what is the probability of getting a king? In a bag, there are 5 red balls and 7 black balls. What is the probability of getting a black ball?
How do you calculate probability example?For example, if the number of desired outcomes divided by the number of possible events is . 25, multiply the answer by 100 to get 25%. If you have the odds of a particular outcome in percent form, divide the percentage by 100 and then multiply it by the number of events to get the probability.
