The total number of possible trios is the number of different ways that 3 things can be selected from a set of 7, which is (7*6*5)/(3*2*1) = 35. The number of possible trios that don't include you is the number of different ways that 3 things can be selected from a set of 6, which is (6*5*4)/(3*2*1) = 20. Therefore, the number of times you went to the park that year is 35 - 20, or 15.jrh150482https://www.blogger.com/profile/10502831081969372299noreply@blogger.comtag:blogger.com,1999:blog-38193052.post-21756591984028330412015-09-16T19:10:09.796-03:002015-09-16T19:10:09.796-03:00Não... mas se quiser me adicionar, meu perfil é es...Não... mas se quiser me adicionar, meu perfil é <b><a href="http://www.facebook.com/pccmfilho" rel="nofollow">esse aqui</a></b>.PC Filhohttps://www.blogger.com/profile/16547063456626761789noreply@blogger.comtag:blogger.com,1999:blog-38193052.post-82647216616353800982015-09-16T17:18:08.052-03:002015-09-16T17:18:08.052-03:00PC, seu blog tem página no Facebook?
