a + b + c + d = 10 a+ b+c+ d = 10? To solve this problem, we use a technique called "stars and bars," which was popularized by William Feller. We create a bijection between the solutions to. a + b + c + d = 10. a + b + c + d = 10 a+b+c+d = 10 and sequences of 13 digits, consisting of ten 1's and three 0's

Feb 27, 2019 · Example Question From Combination Formula. Question 1: Father asks his son to choose 4 items from the table. If the table has 18 items to choose, how many different answers could the son give? Solution: Given, r = 4 (item sub-set) n = 18 (larger item) Therefore, simply: find “18 Choose 4” We know that, Combination = C(n, r) = n!/r!(n–r)!

• ### examples: probability using permutations and combinations

We can use permutations and combinations to help us answer more complex probability questions. Example 1. A 4 digit PIN is selected. What is the probability that there are no repeated digits? There are 10 possible values for each digit of the PIN (namely: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9), so there are 10 × 10 × 10 × 10 = 10 4 = 10000 total possible PINs
