The probability that all 3 cards drawn are diamonds is approximately 0.012941.
Solution
To find the probability that all 3 cards drawn from a shuffled deck of 52 cards are diamonds, we need to calculate the probability of drawing 3 diamonds in a row.
The probability of drawing a diamond on the first draw is
since there are 13 diamonds in a deck of 52 cards.
The probability of drawing a diamond on the second draw, given that the first card drawn was a diamond, is
since there are now 12 diamonds left in a deck of 51 cards.
The probability of drawing a diamond on the third draw, given that the first two cards drawn were diamonds, is
since there are now 11 diamonds left in a deck of 50 cards.
Therefore, the probability that all 3 cards drawn are diamonds is the product of these probabilities:
Let’s calculate this probability.

To find the probability of drawing 3 diamonds from a shuffled deck of 52 cards, we can start by noting that there are 13 diamonds in the deck. The probability of drawing the first diamond is
. For the second draw, there will be 12 diamonds left and 51 cards total, giving a probability of
. For the third draw, there are 11 diamonds left and 50 cards total, leading to a probability of
.
Now we multiply these probabilities together:
When rounded to six decimal places, the probability is
.
If you’re wondering about common mistakes in calculating probabilities, one key pitfall is forgetting to adjust the number of favorable outcomes and total outcomes after each draw. Miscounting the remaining cards or failing to reduce fractions properly can lead to incorrect probabilities. It’s always advisable to write down the calculations step-by-step!
