After a red disc is picked, there are 4 remaining, from a total number of 14. Yet some more questions from the Cambridge HSC Maths General 2 textbook. Mathematically, we have that: This rule is named the multiplication or product rule of probability. Thus the probability of drawing a spade is given by: Now, the probability of obtaining a 6 with a dice is given by: Now, these events are independent, and hence we have that the probability of both these events occurring is given by: It has been found that development of lung cancer and AIDS have no direct correlation. 3 0 obj endobj Hence we have that the probability of obtaining a sum of upon rolling two dice is given by: Note: This method may be used for all two-stage experiments involving independent events however, it must not be used for events involving dependent events. Starting from 2020, the state moves into the first HSC of the new syllabus for advanced and extension maths after using the old syllabus for more than 20 years. To calculate the probability of her to not win is equal to the complement of her winning. Since there exist 4 suits with 13 cards each in a standard deck we thus have. Another marble is then drawn out. i.e. To obtain the probability of independent mutually exclusive events occurring sequentially (any occurrence of two events is called a – two stage experiment, in which one event is first, followed by another), one may simply multiply the respective probabilities of each event occurring, to obtain the resultant probability. Tutorial on finding the probability of an event. Here we will understand and use the concepts of a probability density function of a continuous random variable. Need help? Here we firstly set up our tree diagram, with our possible outcomes being, prize or no prize. That is: Now, from the addition rule for probabilities we have that (Not specifically included in course – if students would like more information refer to “A Higher School Certificate Course in Mathematics, Form 6” by Jim Coroneos): Recall that is the mathematical symbol for “and”. Pages 2–11. Of course, use of the complementary event is not always possible (or easy) so be sure to check whether the complementary event applies or not. That is, the probability of the event occurring is: Of course, we assume that every outcome is equally likely to occur. Find and download all your Maths HSC Past Papers here. Example 3 A Roulette wheel at a casino has 37 numbers: 0 to 36. Now, it should be quite obvious that in any experiment, either an event occurs, or the complementary event occurs (that is to say that either will occur or will not occur). Exam-type questions and worked solutions. Hence as there are blue or white balls then the probability of obtaining a ball that is not red is given by: Now, since the total number of events that may occur is always greater than or equal to the number of ways a certain event may occur, then it follows that the probability of an event occurring is always less than or equal to one. Similarly for the red discs, initially there are 5 red discs from 15 in total.
