4 100 Basic Probability 100 A bag contains some sweets. There 4 toffees, 2 fruit jellies and 2 chocolates. Two sweets are picked at random. What is the probability that the two sweets of the same type?

5 200 Topic 1 200 What is the probability of choosing the letter i from the word probability?

6 300 Topic 1 300 Numbers from 1-50 are written on pieces of paper. What is the probability of drawing a multiple of 12?

7 400 Topic 1 400 A single die is rolled. Find the probability of getting either an odd number or a 3?

8 500 Topic 1 500 You roll two dice. What is the probability that the sum is a 6?

9 100 Topic 2 100 The sample space S contains two events A and B (Venn Diagram). Shade the region of the Venn Diagram representing:

10 200 Venn Diagrams 200 n In a class of 29 students, 22 study Chemistry, 21 study History and 3 study neither. Draw a Venn Diagram representing this situation. Determine the probability that the student: n a)studies both subjects

11 300 Topic 2 300 The sample space S contains two events A and B (Venn Diagram). Shade the region of the Venn Diagram representing:

12 400 Topic 2 400 50 students went bushwalking. 23 get sunburnt, 22 get bitten by ants, and 5 very unhappy people are BOTH sunburnt and get bitten by ants. Determine the probability that a randomly selected student was either bitten or sunburnt.

13 500 Topic 2 500 In a class of 40 students, 19 play tennis, 20 play netball, 8 do not play either of these sports. Determine the probability that the student plays tennis.

14 100 Tree Diagrams 100 Carl is not having much luck lately. His car will only start 80% of the time and his motorbike will only start 60% of the time. Determine the probability that both will start.

15 200 Topic 3 200 Consider a box containing 3 red, 2 blue and 1 yellow marble. We pick two marbles (one at a time). What is the probability of getting two different colors: (with replacement)

16 300 Topic 3 300 A bag contains four red and two blue marbles. Three marbles are selected without replacement. Determine the probability that: a)all are red

21 300 Topic 4 300 What is the probability that a randomly selected student is a female given that the person has their Master’s?

22 400 Topic 4 400 If we randomly select a student, what is probability of the person being a professional given she is a female?

23 500 Topic 4 500

24 100 Topic 5 100 If P(R)= 0.4, P(S) = 0.5 and a)Are they independent events?

25 200 Topic 5 200 A survey revealed that 34% of people are entertained by reading books, 47% are entertained by watching TV, and 19% are entertained by both books and TV. What is the probability that a person will be entertained by either books or TV?
