The correct Answer is:
To find the probability that Ramesh draws a card that bears an even number in black from a standard deck of 52 cards, we can follow these steps: ### Step 1: Identify the total number of cards in the deck. A standard deck of cards contains 52 cards. **Hint:** Remember that a standard deck has 4 suits: hearts, diamonds, clubs, and spades. ### Step 2: Identify the black suits. The black suits in a deck of cards are clubs and spades. **Hint:** There are 2 black suits in a deck. ### Step 3: Identify the even numbers in the black suits. The even numbers in a deck of cards are 2, 4, 6, 8, and 10. Each black suit (clubs and spades) has these even numbers. **Hint:** Count the even numbers available in one black suit and remember that there are two black suits. ### Step 4: Calculate the total number of even black cards. Each black suit has 5 even cards (2, 4, 6, 8, 10). Therefore, in both black suits, the total number of even cards is: \[ 5 \text{ (from clubs)} + 5 \text{ (from spades)} = 10 \text{ even black cards} \] **Hint:** Multiply the number of even cards in one suit by the number of black suits. ### Step 5: Calculate the probability. The probability \( P \) of drawing an even number in black is given by the formula: \[ P(\text{even black}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \] Substituting the values: \[ P(\text{even black}) = \frac{10}{52} \] ### Step 6: Simplify the probability. To simplify \( \frac{10}{52} \): \[ \frac{10}{52} = \frac{5}{26} \] **Hint:** Always simplify fractions to their lowest terms. ### Final Answer: The probability that Ramesh draws a card that bears an even number in black is \( \frac{5}{26} \).
