There has been a theft at the school near to Quiz Master Shop Towers. Luckily there is an eyewitness who saw the thief escaping. The eyewitness has reported that the thief was in school uniform and wearing a blazer, as opposed to a jumper.
Police research has shown that in these cases an eyewitness is correct 80% of the time. It is also known that 85% of the pupils at the school wear jumpers and not blazers, which has increased the chances of finding the culprit.
What is the probability of the thief wearing a blazer?
Think carefully about this - it is harder than it appears.
