Answers
I think you need the questions for practice so I am not sending answers.
Example 1: A coin is thrown 3 times .what is the probability that atleast one head is obtained?
Example 2: Consider the example of finding the probability of selecting a black card or a 6 from a deck 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'?
