Looks like we voted on no vocab test and a take home test on probability. Keep checking the blog for more polls; I liked the democratic decision making process!
Today's update differs by class:
Period B: You have no homework (we did the other classes' homework as our stamp). I am concerned that some of us won't learn what we need to for our take home test. We will have to finish chapter 17 on Monday and Tuesday; however, if you are absent (either because you're just not here or you're at the honors breakfast) you will miss some super important stuff that you need for your take home test. I'm not saying you should skip bingo, but if you're not in class, you're still responsible for what you missed. If you have study hall E or F period I would recommend coming to one of those classes so you're not behind. I have a meeting on Monday and therefore cannot stay after school. I am available during D or H period on Monday, and D,G(lecture hall), and H period on Tuesday.
Periods E and F: Unfortunately, I realized too late (for period B) that I shouldn't have spent so much time on the "Stamp." So, you're homework is to complete the "Stamp" problem provided in class (or found below). This is some probability review! On Monday and Tuesday we'll finish learning about binomial probability so we can ace our take home test!
Have a great weekend!
"Stamp Problem" Homework:
The article "Checks Halt over 200,000 Gun Sales" (San Luis Obispo Tribune) reported that required background checks sometimes block gun sales. The article indicated that state and local police reject a higher percentage of would-be gun buyers than does the FBI, stating, "The FBI performed 4.5 million of the 8.6 million checks, compared with 4.1 million by state and local agencies. The rejection rate among state and local agencies was 3%, compared with 1.8% for the FBI.
a.) What is the probability that a randomly selected gun sale was checked by the FBI and was not rejected?
b.) What is the probability that a sale that was rejected was checked by the FBI?
c.) What is the probability that a randomly selected gun sale was rejected?
d.) What is the probability that a sale that was checked by the FBI was rejected?
