Find alternative Form of Probability, Find the Probability, Find the Value of Pronumerals, Find the Standard Deviation.
The video below is from the Find the Value of Pronumerals sub topic. It has my solution to Question 4 from the 2018 VCAA Maths Methods Multi Choice exam. This type of question relies on an understanding of the basic method of finding a probability value and how to use symmetry to find the value of a pronumeral – 79% of students answered part a correctly and 41% answered part b correctly.
