DO NOW: “Probability & Combinations #1”
The DO NOW must be completed and submitted; you will get a grade AND this is how you will have your attendance recorded for the day. You may simply make a copy of the assignment, show YOUR work and final answer and turn it in; others have taken a picture of their notebook or their calculation showing their handwritten DO NOW work & answer. Either method is acceptable but must be submitted/turned-in via Google Classroom. Don’t forget to go do today’s LESSON after you finish the DO NOW.
What is the probability of getting two fives when you roll two dice? [hint: if you forgot how to do this, you can go watch the video in the lesson assignment]
Explain your reasoning; do NOT just give final answer. You may leave your answer in fraction form, but remember to reduce if necessary.
Answer:
6 sided die, one 5 on each:
1/6 *1/6 = 1/36

LESSON: “Probability & Combinations #1”.
This lesson must be done as well. Problems on future quizzes, tests, and the final will be from some of these lessons, so please take your remote learning and work very seriously. IF INSTRUCTED, you also need to submit classwork to be graded. Again, you may simply make a copy of the assignment, show YOUR work and final answers and turn it in; others have taken a picture of their notebook or their calculation showing their handwritten CLASSWORK work & answers. Either method is acceptable but must be submitted/turned-in via Google Classroom. If you didn’t do the DO NOW, make sure you go back and do it (need for attendance & a grade).
Today’s lesson is a review of what we covered in class last week.
Watch this Khan Academy video on rolling a pair of dice: https://www.khanacademy.org/math/precalculus/x9e81a4f98389efdf:prob-comb/x9e81a4f98389efdf:independent-events-precalc/v/events-and-outcomes-2
WORK TO DO: Answer the following questions CAREFULLY. Explain your reasoning and show any work; do NOT just give final answer. You may leave your answer in fraction form, but remember to reduce if necessary.
1) In your own words, what is a “double” according to the video?
Note: Both dice get the same number.
2) What is the probability of getting a pair of the same numbers?
Note: 1/6 Whatever the first die roll, the second die must match
3) What is the probability of getting either two “4’s” OR two “5’s”?
Note: 1/36 + 1/26 = 2/36=1/18
4) What is the probability of getting a SUM of six when you roll two dice?
Notes: out of 36 possibilities: 1&5, 2&4, 3&3, 4&2, 5&1 = 5/36
