What is the probability that both socks are white?
(2) The probability is greater than 0.4 that both socks will be white.
What is the probability that we get at least two socks of the same color?
Picking the first sock of the two with the same color has the probability of 2/6, and therefore picking the second sock with the same color has a probability of (2−1)/(6−1)=1/5 respectively.
What is the probability of picking a second white sock after first picking a white sock?
The probability of picking a pair of white socks is also 1/2 of 11/23, meaning in order to get the probability of picking any matching pair, you add these two together. The final probability of picking a matching pair of socks is 11/23, or 47.8 percent.
How many black socks are there in a drawer?
A drawer contains 5 black socks and 3 white socks. If two socks were picked at random, what is the probability of getting a matching pair? If four socks were picked at random, what is the probability that only one of them is white? A drawer contains 5 black socks and 3 white socks.
How many pairs of socks can you pick out of?
You can first find the probability of picking, say, a pair of red socks, then multiplying that probability by 3 because you can have 3 possible pairs of socks (with the same color). Another way of solving this is by finding the amount of possibilities with 2 socks of the same color divided by the total amount of possibilities.
How do you choose two socks of the same color?
There are 6 possibilities for choosing two socks of the same color. You can have a pair of red, blue or purple socks. The order does not matter and what that means is that say we have two red socks, r 1 and r 2. We can pick r 1 then r 2 or r 2 then r 1.
How to pull two matching socks in 3 draws?
To pull two matching socks in three draws. you can pull 3 socks of the same color, or 2 socks of one color, and sock of annother color. $\\frac{5{4\\choose2}*16 + 5*{4\\choose3} }{20\\choose3}$ we can keep going with this methodolgy to work up to 4 and 5 4 draws.
