A pack of cards is shuffled and one is drawn at random this happens a hundred times how many times would there be a diamond?

The probability of drawing a diamond in a standard deck of cards is 1 in 4.

The probability of drawing a diamond if this is repeated 100 times is still 1 in 4, which translates to 25 in 100, but since this is a random process you would not expect diamonds exactly 25 times.
