Can you please answer this

1. Casino owners are always looking out for card-counters. Generally people who do well at the card tables will be under suspicion of being a card counter by casino security. Of the people who go to the casino, 10% count cards. Of those card-counters, 40% will do well at the card tables. For those who do not count cards, 15% will do well. If someone does well and is confronted by casino security, what is the probability that they are actually a card counter? 2. Traffic lights in my neighborhood Are terribly timed. There is a 65% chance that I will miss the first of two traffic lights. If I miss the first traffic light, there is a 70% chance that I will miss the second. If I do not miss the first light, there is a 20% chance that I will miss the second light. If I end up missing the second light, what is the probability that I missed the first light? 3. 30% of people who come into the hospital for surgery come in for emergency surgery as opposed to elective surgery. Of those who come in for emergency surgery, there is a 45% chance that they will experience complications with that surgery. For those who come in for elective surgery, there is only a 5% chance of experiencing complications. If a person goes into the hospital and does NOT experience complications, what is the probability that they came in for emergency surgery
