Solution
To solve this problem, we first need to find the total number of football players in all classes.
Step 1: Add the number of players in each class 12 (class 1) + 15 (class 2) + 8 (class 3) + 5 (class 4) = 40 players in total
Step 2: Find the number of players in class 2 and class 3 15 (class 2) + 8 (class 3) = 23 players
Step 3: Calculate the probability The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes. In this case, the favorable outcomes are the number of players in class 2 and class 3, and the total outcomes are the total number of players.
So, the probability that the player is either from class 2 or class 3 is 23 (favorable outcomes) divided by 40 (total outcomes), which simplifies to 23/40.
So, the correct answer is 23/40.
