QueS'lO\" 6 The Rec Centre has analysed its records for customer use of the squash courts and supercircuits classes. They found that the Not yet probability that a customer does not take supercircuits classes is 0.20, the probability that a customer who takes answered supercircuits classes also uses the squash courts is 0.60, and the probability that a customer does not take supercircuits Marked out of classes given that they use the squash courts is 0.30. 3.00 The Rec Centre manager has asked you to use this information to calculate the probability that a customer who uses the squash courts also takes supercircuit classes, the probability that a customer uses the squash courts, and the probability that a customer either uses the squash courts or takes supercircuits classes (or both). Y Remove flag The events of interest are defined as SC for the event "customer takes supercircuits classes" 56\" for the event "customer does not take supercircuits classes" SQ for the event "customer uses the squash courts" 50 for the event "customer does not use the squash courts" Match the words to the correct representation in probability symbols: The probability that a customer uses the squash courts is represented as Choose... 0 The probability that a customer who uses the squash courts also takes supercircuit classes is represented as Choose... v The probability that a customer either uses the squash courts or takes supercircuits classes (or both) is represented as Choose... v Choose... a discrete random variable neither continuous or discrete this is categorical data continuous random variable Question 11 Not yet answered Marked out of 2.00 Y Remove flag Select the correct description for each of the following: Quantity of oil from an oil well, per hour Amount of idle time for a hairdresser Number of people in front of you in the supermarket queue Country of origin Choose...

He uses a 'cheat-checker' algorithm to identify submissions that have a suspiciously high level of similarity to each other, ier submissions which my be copies. The events of interest are defined as: 0 C for the event "submission has been copied" 0 C' for the event "submission has not been copied" 0 S for the event "submission is identified as suspiciously similar to others" 0 S' for the event "submission is not identified as suspiciously similar to others" The lecturer is preparing a tree diagram to explain the probabilities involved to the university proctors. He has the sketch shown below but he has not labelled it yet. Drag and drop the correct labels onto the branches and the tips of the branches to complete the sketch.
