Step 1This is a hypergeometric distribution. We begin with choosing a single left handed person. This is independent of choosing four right-handed people, so by rule of product we multiply. We divide by the number of ways to select 5 people.Step 2                                          (                                    4          1                                      )                                                            (                                    6          4                                      )                                                        (                            10        5                              )
