DUE IN 15 MINUTES PLEASE HELP— Thanks A man and his wife usually ate a barrel of pickles in 12 days; but when the man was away from home it lasted the woman 30 days. How many days would the man be alone eating it.

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?
