On a certain day, the probability that the weather is rainy is 0.40, the probability that it is windy is 0.30, the probability that it is rainy and windy is 0.10. The probability that it is snowy given that it is rainy is 0.10, the probability that it is snowy given that it is not rainy is 0.05. Find the probability that the weather on this day is: 1) neither rainy nor windy. 2) rainy only or windy only. 3) not windy given that it is not rainy. 4) snowy. 5) rainy given that it is snowy.
