Problem Statement: A card is drawn from each of two well shuffled cards. Probability that at least one of them is ace is?

Solution:

Step 1: Understand the problem

We need to find the probability of drawing at least one ace from two shuffled cards.

Step 2: Find the total number of outcomes

Since we are drawing two cards, the total number of outcomes is:

52 * 51 = 2,652

Step 3: Find the number of outcomes that satisfy the condition

We can calculate the number of outcomes where at least one of the cards is an ace by finding the total number of outcomes where:

- The first card is an ace and the second card is not an ace
- The first card is not an ace and the second card is an ace
- Both cards are aces

Number of outcomes where the first card is an ace and the second card is not an ace:

4 * 48 = 192

Number of outcomes where the first card is not an ace and the second card is an ace:

48 * 4 = 192

Number of outcomes where both cards are aces:

4 * 3 = 12

Total number of outcomes where at least one of the cards is an ace:

192 + 192 + 12 = 396

Step 4: Find the probability

The probability of drawing at least one ace from two shuffled cards is:

396/2,652 = 0.149 or 14.9%

Conclusion: The probability of drawing at least one ace from two shuffled cards is 0.149 or 14.9%.
