Spade: 1 in 4
Ace: 1 in 13
The probability that it is a spade when drawn is 13/52 or 1/4.
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.
Probability of drawing a heart: 1/4 Probability of drawing a club: 1/4 Probability of drawing a heart or a club: 1/4 + 1/4 = 2/4 = 1/2
The probability of drawing an Ace from a standard deck of 52 cards is 4 in 52, or 1 in 13, or about 0.07692.
Assuming there are no Joker cards the chance is one in twenty six. There are fifty two cards in a pack and only two of them are black kings.

It is 1/4.
There are four suits in a deck of cards with equal numbers of cards per suite, so the chance of drawing a heart is 1/4 and a spade is 1/4 too. To draw a heart, replace it, then draw a spade, 1/4x1/4 = 1/16, or a 6.25% chance.

The probability of a random card from a pack of 52 cards being a spade or a face card is 11 in 26. There are 13 spades and 12 face cards, with 3 of the face cards being spades, so there are 22 possible cards (13 + 12 - 3) that are spades or face cards. The probability is 22 in 52, or 11 in 26.
