I assume you are selecting two socks (one at a time) from the drawer to wear (for example).
There are 6 white + 3 black + 3 brown + 8 gray = 20 socks in all
So the probability that the first sock chosen to be white is 6/20 since there are 6 socks and 20 socks in total. 6/20 reduces down to 3/10.
The probability that the second sock chosen is also white is 5/19 since there are now only 5 white socks left to be chosen and 19 socks in total (since one sock has been taken out).
Thus the probability of both socks being white is:
probability = 3/10 x 5/19
= 3/38
The probability is 0.
The probability of choosing a red or black card from a standard deck of 52 cards is 52 in 52, or 1 in 1. In other words, it will happen no matter what.
It is 2/52 or 1/26.
(10/29)(9/28)= 0.110837438 or about 11.1%
If you draw enough balls, without replacement, the probability is 1.The answer depends onhow many balls are drawn, andwhether or not they are replaced.Unfortunately, your question gives no information on these matters.
The probability is 0.
The probability, or probility, even, is 0 since tere can be no such thing as "choosing red card of the black".
A sock drawer has 2 blue pair, 4 white pair, 4 black pair. What is the probability you will pick out a black pair?

A laundry bag contains 160 black socks and 300 red socks. 1940 black socks must be added so that the probability of choosing a black sock is 7 of 8.
(10/29)(9/28)= 0.110837438 or about 11.1%
Well, if this drawer contains that amount of socks of each color, then you will have a 1:5 probability that the the first sock you draw will be white. 7+4+9=20 4(white)/20(in all) 1(white)/5(all) :D
Open the drawer. On the inside on both sides is a screw with a corresponding nut on the outside of the drawer holding the rail to the drawer. Remove these two screws and the rails will slide out of the drawer. When replacing the drawer make sure the rails slide into the slots on the drawer.
depends on the two guinea pigs genotypes. could be anywhere from 75 to 100 percent.
The answer depends on whether or not the first coin is replaced before choosing the second. Unfortunately, that critical information is not provided.
