Chapter 1. Ex 19

Drawing two cards from 52, what is the probability that the second card has a higher face value than the first?

The probability that the second card has the same face as the first is \(\frac{4-1}{52-1}=\frac{3}{51}\) (since there are only four cards with the same face).

The probability that the second card will be different(lower or higher) from the first is \(\frac{51}{51}-\frac{3}{51}=\frac{48}{51}\).

The chance than the card will be higher is the same as the card will be lower.

So that,the probability that the second card has a higher face value than the first is \(\frac{\frac{48}{51}}{2}=\frac{24}{51}\)
