Question 2 Choose from Impossible Certain Likely Unlikely Evens to describe the probability of each of the following. An ordinary coin when tossed will show “heads”. Everyone in a class at school will have the same colour of hair. You will pick a black ball out of a bag only containing black balls. An ordinary die will land on an 8. Question 3 For the spinner shown find: Which colour is the spinner most likely to land on? Least likely to land on? How many more times likely is Black than Yellow? Redesign the spinner so that Black is four times more likely than yellow. Question 4 A bag contains 19 balls, 7 are red, 8 Green and 4 White. One disc is selected at random. Are all outcomes equally likely? Explain your reasoning. Calculate, the probability that it Red. How many Green balls would you have to add so that the probability of picking white is 0.16. Question 5 A fair coin is tossed and a die is thrown. Make out a sample space for this experiment and find the probability of getting a tail on the coin and an odd number on the die.
