Answer: 2
I'm really struggling with this concept, hoping you guys could help me out.
The pairs have been separated out and you must take out a pair of socks.
Consider these problems and provide a calculation for each:
Probability of drawing a matching pair if you randomly draw 2 socks?
Probability of drawing a matching pair if you randomly draw 3 socks?
(Repeats up to randomly drawing 5 socks)
For 2 socks I got the following:
40 possible socks * 39 other possible socks = 1560 possible combinations of socks / 2 (to remove duplicate matches) = 780
For each set of socks, there are 8. 8 * 7 (7 other socks to each being matched) = 56 possible combinations in each set of socks / 2 to remove duplicates = 28 possible combinations of socks in each set.
28 / 780 = 0.036 probability of drawing a pair when drawing 2 socks from the drawer.
