The probability is calculated as a division between the number of possibilities that satisfy a condition and the number of total possibilities. Then, the probability that the first card is diamonds is:

Because the deck has 52 cards and 13 of them are diamonds.
Then, if the first card was diamonds, the probability that the second card is also diamond is:

and
. This is:

Answer:
Mr. Smiths class has 12 students and Mrs. Brown's class has 10 students.
