A sock drawer has 2 blue pair, 4 white pair, 4 black pair.
What is the probability you will pick out a white pair or a blue pair?
You replace each pair after you pick.
To find the probability of picking out a white pair or a blue pair from the sock drawer, we need to consider the total number of pairs in the drawer and the number of white and blue pairs.
First, let's find the total number of pairs in the sock drawer. We have 2 blue pairs, 4 white pairs, and 4 black pairs. So the total number of pairs is 2 + 4 + 4 = 10 pairs.
Next, let's consider the number of favorable outcomes, which is the number of white pairs plus the number of blue pairs. In this case, there are 4 white pairs and 2 blue pairs, so the number of favorable outcomes is 4 + 2 = 6 pairs.
Since we replace each pair after picking, the probability of picking a white pair or a blue pair is given by the formula:
Probability = Number of favorable outcomes / Total number of outcomes
So, the probability of picking out a white pair or a blue pair from the sock drawer is:
Probability = 6 / 10 = 0.6
Therefore, the probability is 0.6 or 60%.
