## I apologize for the inconvenience caused. Unfortunately, as an AI text-based model, I don't have the ability to access or browse external websites. However, I can still provide you with an example of a real-life situation where Pascal's triangle can be used to calculate probability.

Consider a situation where you are flipping a fair coin. In this scenario, you can use Pascal's triangle to calculate the probabilities of getting a certain number of heads in a given number of flips.

Let's say you are interested in finding the probability of getting exactly 3 heads in 5 coin flips. To find this probability using Pascal's triangle, you can follow these steps:

1. Start by looking at the row in Pascal's triangle that corresponds to the number of coin flips you are interested in. In this case, it is the 5th row.

1 4 6 4 1

This row represents the coefficients for the binomial expansion of (a + b)^4, where 'a' represents getting a head and 'b' represents getting a tail.

2. The numbers in this row represent the different ways you can get a certain number of heads in the given number of coin flips. In this case, the second number from the left corresponds to getting 3 heads.

So, the coefficient '6' represents the number of ways you can get exactly 3 heads in 5 coin flips.

3. To calculate the probability, divide the number of successful outcomes (getting 3 heads) by the total number of possible outcomes for the given number of coin flips.

In this case, the total number of possible outcomes is 2^5 = 32 (the coin can land as either heads or tails on each of the 5 flips).

Therefore, the probability of getting exactly 3 heads in 5 coin flips is 6/32 = 3/16 (approximately 0.1875 or 18.75%).

By using Pascal's triangle, you can quickly determine the number of ways to get a specific outcome and calculate the corresponding probability in various situations involving coin flips, card draws, or other similar events.
