A die is rolled and a coin is tossed, find the probability that the die shows a number less than 5 and the coin shows a head.

To find the probability that a die shows a number less than 5 and a coin shows a head, we need to consider the probabilities of each event separately and then combine them.

First, let's consider the die. A standard die has 6 faces numbered from 1 to 6. The event that the die shows a number less than 5 includes the numbers 1, 2, 3, and 4. So, there are 4 favorable outcomes for the die:

\[
1, 2, 3, 4
\]

The probability \( P(\text{die shows less than 5}) \) is given by the ratio of the number of favorable outcomes to the total number of possible outcomes:

\[
P(\text{die shows less than 5}) = \frac{4}{6} = \frac{2}{3}
\]

Next, let's consider the coin. A standard coin has two faces: heads and tails. The probability \( P(\text{coin shows head}) \) of getting a head is:

\[
P(\text{coin shows head}) = \frac{1}{2}
\]

The events of rolling the die and tossing the coin are independent, so we can find the combined probability by multiplying the probabilities of each individual event:

\[
P(\text{die < 5 and coin = head}) = P(\text{die shows less than 5}) \times P(\text{coin shows head}) = \frac{2}{3} \times \frac{1}{2} = \frac{2}{6} = \frac{1}{3}
\]

Therefore, the probability that the die shows a number less than 5 and the coin shows a head is \( \frac{1}{3} \).
