Tell whether the question can be answered using combinations or permutations. Explain your choice, then answer the question. You are required to complete 3 out of 8 works on your science menu in order to master the unit. In how many ways can you choose works?
This is a combination because order is not important. It does not matter which work I choose to do first. As long as I complete 5 I will master the unit. I could do works A, B, C or works C, B, A it doesn't matter the order. 8 C 3 = 56 ways to choose the works

Tell whether the events are mutually exclusive or overlapping events, then answer the question. Refer to a bag containing 7 tiles lettered, B, E, Y, O, N, C, and, E You choose a letter at random. What is the probability that you choose a "O" or a vowel?
Overlapping because O is a vowel. 1/7 + 3/7 - 1/7 = 3/7

Tell whether the question can be answered using a combination or permutation. Explain your choice, then answer the question. You have 12 favorite songs and want to make a playlist containing 5 of those songs. In how many ways can you arrange the songs?
Permutation, because order does matter. If you arrange the songs in a different order, you create a new playlist. 12 P 5 = 95,040

Tell whether the events are mutually exclusive or overlapping events, then answer the question. Refer to a bag containing 7 tiles lettered, B, E, Y, O, N, C, and, E You choose a letter at random, replace it, and choose a second letter. What is the probability you choose an "E" then a consonant?
Mutually exclusive because E is a vowel, not a consonant. 2/7 x 4/7 = 14/49 = 2/7
