Wednesday HW!

You must always check your answers/correct your homework to receive full credit. This is the policy for the remainder of the school year. If you do not do so, you will not be given full credit. 

Why? (is Carofano making me do this)

• Learning = making mistakes and correcting them
• Learning = using a given answer to work backwards and develop your understanding
• That's the whole point of our homework--to learn and practice for our quizzes tests!

Wednesday Homework:

1.) Please complete the following in your textbook:

• Page 340: 11, 13
• Page 342: 28abcd, 29abd 

2.) CHECK YOUR ANSWERS! Use a different color pen/pencil to grade yourself/make corrections. If you got something wrong, figure out why! That's how we get better at stuff!

• 11, 13, and 29 can be found in the back of the book.
• Here are the answers to 28:
• 28a.) lemon and lemon and lemon = (0.3)^3 = 0.027
• 28b.) no fruit and no fruit and no fruit = (0.5)^3 = 0.125
• 28c.) bell and bell and bell = (0.1)^3 = 0.001
• 28d.) no bell and no bell and no bell = (0.9)^3 = 0.729

Bonus Stamps (Due Friday): + 4 stamps

• Answer the question below (#7 from our slides about roulette) "the long way."
• You must show ALL work
• Your answer should match our answer from Thursday's class when we did this "the short way" 
• Question:
• Suppose we play roulette 4 times...
• What is the probability that the 4 spins are not all red?
• This means we could have 0 red, 1 red, 2 red, or 3 red (just not all 4 red)
• Your challenge:
• Calculate the probability of 0 red, exactly 1 red, exactly 2 red, 3 red
• Add these for the probability that our 4 spins are "not all red"
• Answer should = 0.94966
