Assignment 3: The Case of Ms. Williams (boys vs. girls). January 30, 2008. The case of Ms. Williams (thinks she is biologically wired to have only boys because she had 3 boys in a row). We did a random number generation on a TI-86 calculator, using only the numbers 0 and 1, assuming that 1s were boys:. EXACTLY three boys in succession occurs four times (in bold and underlined). The event “exactly three boys in succession” is likely to occur…. 4 / (100-2) = .04. 6 / (100-2) = .06. 61/100 = .61 (boys).

Filed under: Lab 1. 8212; rclaa1cb @ 3:09 am. 1) Q: What is meant by a “random event” and how does it differ from a “systematic event”? A random event is impossible to predict due to the fact that there are too many unpredictable factors that influence its occurence that we cannot know in advance. A systematic event is one that is created by bias. 2) Q: Is it possible to predict correctly any future event? Laquo; Previous Page.

Quela Carlson and Melissa Shepherd. Assignment #6: Calculating with Conditional Probability: Bayesian Probability. Imagine you are a juror for a murder trial. The victim, a 29-year-old woman, was stabbed to death in her home. The defendant is a 30-year-old man, who is a neighbor of the victim. After questioning a number of the victim’s neighbors, police brought the defendant in for further questioning, and they noticed he had a cut on his arm.

Putting this into the formula, we are looking for P(Guilty/Positive Test). So after plugging in the rest of the data, the formula will be…. P(G/pos) = P(G) P(pos/G)/{P(G)P(pos/G) P(pos/NG) P(NG). We know that the original P(G) is .10 (therefore P(NG) is .9) and P(pos/G) = .99 (therefore P(pos/NG) is .01). 124; 1 Comment. We cho...
