The probability of drawing a red four and then a blue four is:

P = 1/100

How to get the probability?

We know that there are 10 cards in total, then the probability of drawing a red four (there is only one of these cards) is:

p = 1/10

Now we put the red four again, the probability of getting a red blue is computed in the same way:

q = 1/10

The probability for both events happening consecutively is:

P = p*q = (1/10)*(1/10) = 1/100
