Julie’s lolly bag contains two chocolates, two boiled lollies and a gum ball. She eats two of them, randomly, one after the other (that is, with no replacement.) a Use a simple tree diagram to represent this situation.
b What is the probability the lollies she eats will be a chocolate, followed by a boiled lolly?
c What is the probability both the lollies will be the same?
d What is the probability at least one of the lollies will be a chocolate?
e She decides that if the second lolly is the same as the first, she will replace it and try again until she gets a different lolly. What now is the probability at least one of the lollies will be a chocolate?
(Hint: There is no need to extend the tree diagram. Think of what this situation is
equivalent to.)

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
