Probability without replacement formula - Math Help

Webbdecide whether the sampling is with or without replacement. If it is without replace-ment, decide whether the sample is ordered (e.g. does the question say anything about the ﬁrst object drawn?). If so, then use the formula for ordered samples. If not, then you can use either ordered or unordered samples, whichever is convenient; they WebbLet E = event of getting a head on the first roll. This implies you can get either a head or tail on the second roll. E = { HT, HH }. P ( E) = 2 4. Find the probability of getting at least one (one or two) tail in two flips. Let F = event of getting at least one tail in two flips. F = { HT, TH, TT }. P ( F) = 3 4. Try It 3.6 jessica livingston

WebbSolved Examples Using Permutation Formula Question 1: Find the number of permutations if n = 9 and r = 2. Solution: Given n = 9 and r = 2. Permutation = n P r = n!/ (n−r)! = 9! / (9-2)! = 9! /7! = 72 Thus, the number of permutations = 72 Question 2: Find how many ways you can rearrange letters of the word “BANANA” all at a time.
