Lesson set: Understand the conditional probability of A given B as P(A and B)/P(B): Four video lessons: Interpret conditional probabilities; identify conditional probability in a two-way table and in a tree-diagram; interpret independent variables using conditional probabilities. Aligns with CP-A.3.
If you randomly guess the answer to a true/false question on an exam, you are equally likely to select a correct answer or an incorrect answer. To calculate the probability of an event A when all outcomes in the sample space are equally likely , count the number of outcomes for event A and divide by the total number of outcomes in the sample space.
Conditional Probability and Independence Section. The probability of one event occurring given that it is known that a second event has occurred. The two-way table below displays the World Campus enrollment from Fall 2015 in terms of level (undergraduate and graduate) and biological sex.
A Possible answers 1 A computer network is a system of interconnected computers that share files and other resources 2 They enable us to get the most from our peripherals. For example, printers, scanners and high speed modems or routers can be shared by a great number of users on the same network.
answer is not a probability. [2 marks] Examiners report This question was generally well answered by many of the candidates. Many found the conditional probability in part b) easier compared to previous sessions, since they were able to write it down directly from the table. A number of candidates found the final
Probability Worksheet 1. A single die is rolled. Find the probability of rolling a 2 or an odd number. 2. Suppose that 37.4% of all college football teams had winning records in 1998, and another 24.8% broke even. What is the probability that a randomly chosen college football team had a losing record in 1998? 3. A couple plans to have four ...
Have the students use the Two Colors game to perform experiments that will demonstrate conditional probability. There are three closed boxes. One box contains two green balls, another one contains two red balls and the last one has one red and one green ball. If students use the software, the computer will shuffle the boxes.
