a sock drawer has 2 blue pair, 4 white pairs, 4 black pair. what is the probability you will pick out a white pair or blue pair? you replace each pair after your pick

i think it 4/10 im not for sure

Do you pick two? If you are trying for a matched pair, why would you replace the first one?

There are a total of 20 socks. You can either pick white and then white, or blue and then blue. Add the two probabilities.
(8/20)^2 + (4/20)^2
= (2/5)^2 + (1/5)^2
= 5/25 = 1/5

Well, let's use humor to tackle this probability question!

Picking out a white pair or a blue pair from that sock drawer is like hoping for a colorful surprise in a bag of marshmallows.

First, we need to find the total number of pairs in the sock drawer. There are 2 blue pairs + 4 white pairs + 4 black pairs, so a grand total of 10 pairs.

Now, if we're only interested in selecting a white pair or a blue pair, we need to count those specifically. We have 4 white pairs + 2 blue pairs, making it a miraculous sum of 6 desirable pairs.

To find the probability, simply divide the number of desirable pairs (6) by the total number of pairs (10).

So, the probability of pulling out a white pair or a blue pair would be 6/10, which in simplified form is 3/5.

Remember, though, that probability is like the weather forecast - it can only predict the likelihood of an event, not guarantee the outcome. Happy sock picking!

To find the probability of picking out a white pair or blue pair, we need to calculate the total number of favorable outcomes (white pair or blue pair) and divide it by the total number of possible outcomes.

The total number of favorable outcomes is the sum of the number of white pairs and blue pairs, which is 2 (blue pairs) + 4 (white pairs) = 6.

The total number of possible outcomes is the total number of pairs in the drawer, which is 2 (blue pairs) + 4 (white pairs) + 4 (black pairs) = 10.

Therefore, the probability of picking out a white pair or blue pair is 6/10, which simplifies to 3/5.

So, your initial intuition is incorrect. The correct probability is 3/5.

To calculate the probability of picking out a white pair or blue pair, we need to determine the total number of pairs in the sock drawer and the number of white pairs and blue pairs.

Given:
- 2 blue pairs
- 4 white pairs
- 4 black pairs

To find the probability, we divide the number of favorable outcomes (picking a white or blue pair) by the total number of possible outcomes (all pairs in the drawer).

Favorable outcomes = number of white pairs + number of blue pairs = 4 + 2 = 6
Total number of possible outcomes = total number of pairs in the drawer = 2 + 4 + 4 = 10

So, the probability of picking out a white pair or blue pair is:
Probability = Favorable outcomes / Total number of possible outcomes = 6 / 10 = 0.6

Therefore, the probability of picking out a white pair or blue pair is 0.6, which can be written as a fraction as 6/10 or simplified as 3/5.
