a sock drawer has 2 blue pair,4 white pair,4 black pair? what is the probability you will pick out a black pair ?

i think is 2/10 that how i get my answer but not for sure that correct

depends if the socks are bundled in pairs or as singles.

If in pairs, ...
you have 10 pairs of which 4 are black, you want to pick one black pair.
prob = 4/10 or 2/5

if they are singles, ...
you have 8 black, 8 white, and 4 blue socks for a total of 20 socks.
you want 2 consecutive blacks
prob = 8/20 x 7/19 = 56/380 = 14/95

Well, let's calculate it together! To find the probability of picking out a black pair, we need to divide the number of favorable outcomes (the number of black pairs) by the total number of possible outcomes (the total number of pairs in the drawer).

In this case, the number of black pairs is 4, and the total number of pairs is 2 (blue) + 4 (white) + 4 (black) = 10. So, the probability of picking out a black pair is 4/10, which simplifies to 2/5 or 40%.

So, you got it right! The probability of picking out a black pair from the sock drawer is indeed 2/10 or 20%.

To find the probability of picking out a black pair from the sock drawer, you need to know the total number of pairs of socks in the drawer.

In this case, the total number of pairs of socks is 2 (blue) + 4 (white) + 4 (black) = 10 pairs.

The probability of picking out a black pair is calculated by taking the number of favorable outcomes (black pairs) divided by the total number of possible outcomes (all pairs).

So, the probability of picking out a black pair is 4 (black pair) / 10 (total pairs) = 4/10 = 2/5.

Therefore, the probability of picking out a black pair from the sock drawer is 2/5.

To find the probability of picking out a black pair from the sock drawer, you need to determine the total number of pairs in the drawer and the number of black pairs specifically.

In this case, the total number of pairs in the drawer is 2 (blue pairs) + 4 (white pairs) + 4 (black pairs) = 10 pairs.

The number of black pairs in the drawer is 4.

So, the probability of picking out a black pair can be calculated as:

Number of black pairs / Total number of pairs = 4 / 10

Simplifying this fraction, you get:

4/10 = 2/5

Therefore, the probability of picking out a black pair from the sock drawer is 2/5.
