Answer:
0.5 probability of pressing the button that doesn't work GIVEN that no candy is received.
Step-by-step explanation:
1) The probability of pushing the button that never works: 1/10 = 0.1
2) The probability of pushing one of the buttons that work half the time:
2/10 = 0.2
The probability of (2) not working = 0.5
Overall probability of (2) pressed and not working = 0.5 * 0.2 = 0.1
Probability of non working button being pushed GIVEN no candy is received will be: 0.1 / (0.1+0.1) = 0.1/0.2 = 0.5
