c. Probability of drawing a card divisible by 10: To find how many cards are divisible by 10, we just need to count how many multiples of 10 are in the deck. There are 4 multiples of 10 between 1 and 40 (10, 20, 30, 40). The probability of drawing a card divisible by 10 is: 4/40 = 0.1% So, the probabilities for drawing cards divisible by 3, 5, and 10 are 32.5%, 20%, and 10% respectively.
