1. A student is randomly selected from a class where 35% of the class is left-handed and 50% are sophomores. We further know that 5% of the class consists of left-handed sophomores. Create a Venn diagram to represent the situation and use it to find the following probabilities. (a) What is the probability of selecting a student that is either left-handed OR a sophomore? (b) What is the probability of selecting a right-handed sophomore? (c) Are the events selecting a left-handed student and selecting a sophomore mutually exclusive? ______ Why?

Step 1
We know that 35% of the class is left-handed, so the probability of selecting a left-handed student is 0.35. Show more…

There are 15 freshmen and 17 sophomore students in a classroom. We randomly select two students. Suppose the students were selected with replacement. a) If the first student was a freshman, what is the probability that the 2nd student is also a freshman? b) If the first student was a sophomore, what is the probability that the 2nd student was a freshman? Suppose the students were selected without replacement. c) If the first student was a freshman, what is the probability that the 2nd student is also a freshman? d) If the first student was a sophomore, what is the probability that the 2nd student was a freshman? Be sure to include at least 4 decimal places, if needed.

According to Scientific American, 15% of people are left-handed. In a classroom with 100 students there are 10 left-handed seats available. What is the probability that it will be short of left-handed seats? Identify an appropriate probability model and express this probability. a) X = number of left-handed seats, X ~ B(10, 0.15); P(X > 10) b) X = number of left-handed students, X ~ B(100, 0.15); P(X ≤ 10) c) X = number of left-handed students, X ~ B(100, 0.15); P(X > 10) d) X = number of left-handed students, X ~ B(100, 0.85); P(X > 10) e) X = number of left-handed seats, X ~ B(100, 0.15); P(X > 10)
