The probability of rolling a 4 first and a 2 second is
.
Solución
Let the first roll be
and the second roll be
.
Since the die is fair, the probability of any specific outcome on a single roll is
-
The probability of rolling a 4 on the first roll (
) is -
The probability of rolling a 2 on the second roll (
) is
Since the rolls are independent, the combined probability is the product of the two individual probabilities:
Thus, the probability of rolling a 4 first and a 2 second is
.

The Deep Dive
The probability of rolling a specific number on a die, such as a 4, is
. The same applies to rolling a 2 on the second roll. Since the rolls are independent events, we can multiply the probabilities of each event together:
So, the probability is
.
