Probability of selecting the winning horse
- Let's consider the total number of ways Mr. A can select 2 horses out of 5. This can be calculated using combinations, denoted as C(5, 2) = 10.
- Since Mr. A is selecting randomly, each pair of horses has an equal chance of being selected.
- Now, let's calculate the number of ways Mr. A can select the winning horse out of the 2 he chose. There are 2 ways for him to select the winning horse.
- Therefore, the probability of Mr. A selecting the winning horse is 2/10 = 1/5.
Calculating p
- We are given that the probability is p/q, where q is the total number of ways Mr. A can select 2 horses out of 5, which is 10.
- So, p = 1, as we calculated the probability to be 1/5.
- Therefore, p = 1.
Hence, the value of p is 1.
