The Land Transport Safety Authority of New Zealand conducted a survey on public attitudes to road safety and found that 78% of New Zealanders agreed that New Zealand roads are safer to travel on. Sixty-six per cent of New Zealanders believed that drink-driving laws aimed at reducing the road toll are effective. Suppose that 57% of New Zealanders who said that New Zealand roads are safer to travel on believed that drink-driving laws aimed at reducing the road toll are effective. What is the probability of randomly selecting a New Zealander who:
(a) says that New Zealand roads are safer to travel on and believes that drink-driving laws aimed at reducing the road toll are effective
(b) neither says that New Zealand roads are safer to travel on nor believes that drink-driving laws aimed at reducing the road toll are effective
(c) says that New Zealand roads are not safer to travel on but believes that drink-driving laws aimed at reducing the road toll are effective?
