Mustafiz has 77 balls which are labeled with the numbers from 1 to 77. He draws out a ball from the bag, records down the number and then puts it back in the bag. He does this a total of 4 times (hence has 4 numbers). Now answer the following questions. i. What is the probability that all the numbers are different? [Give your answer upto 4 decimal places] ii. What is the probability that at least 2 of the numbers are equal? [Give your answer upto 4 decimal places]
