    algebra 2 help

    The next three questions refer to the information in this question.

    Groups of students will be created from the three lists below. A group of students will contain exactly one student from each list.

    List 1||| List 2||| List 3
    Alice ||| Ben ||| Cameron
    Amy ||||Barry ||| Carley
    Annabel |||||||||Caren
    Anastasia


    A. How many different groups of students are possible?
    B .One of the possible groups is to be randomly chosen. What is the probability that the group will contain Barry? Show all of your work and explain your answer.
    It will be greatly appreciated if someone answered this for me

    Can you clarify, is that 4 in list 1, 2 in list 2 and 3 in list 3?

    For each of the 4 options in list 1 there is 2 options in list 2. For each in list 2 there are 3 options in list 3. So the number of different options is 4*2*3=24. 24 different groups.

    Barry is in group 2. There are two choices in group 2. You must have one person from each list in each group so half the groups will contain Barry. So the probability is 0.5.
