P(A given B')=[P(A)-P(AnB)]/[1-P(B)].
In words: Probability of A given B compliment is equal to the Probability of A minus the Probability of A intersect B, divided by 1 minus the probability of B.

compliment- it's a word for the probability minus one, so it something has a .6 probability, the probability(compliment) it woun't occur is .4 The answer for the Statistic Crossword Puzzle is "odds"
Define your event as [A occurs and B does not occur] or as [A occurs and B' occurs] where B' is the complement of B. Equivalently, this is the event that [A and B' both occur].
The probability is 1/6.
There are 7 days in a week. One of those is Sunday. Therefore the probability at any given time that tomorrow will be Sunday is 1/7.
Given the way you have worded the question I take it to mean, what is the probability of drawing at least one spade?We can do this most easily by asking first, what is the probability of drawing no spades on each of the 80 times. This is 39/52. The probability of doing this 80 times is (39/52)80.Then the probability of not doing this is 1 - (39/52)80, which is quite close to one. The probability of drawing at least one spade is almost one.
