How do you compute this
My sock drawer contains two red socks, two white socks, and two blue socks. For three days in a row, I pull out two socks out of my sock drawer at random. What is the probability that I get matching socks on all three days?
+163 probability is defined by the
amount of times when it is true/ total amount of times (or false + true in most cases)
the total is 6! or 6*5*4*3*2*1
since we have the pair's of socks over 3 days we take every other integer to multiply
6*4*2
so if we take 6,4,2 out of the denominater
\(\frac{1}{5*3*1}\)
since 1*x = x we can take this out of the equation
5*3 = 15
the solution is \(\frac 1 {15}\)
