A drawer has 4 red socks and 4 blue socks. If 3 are drawn, what is the probability of a match?
1.0
There are only two colors, so the 3rd sock must match one of the previous two.
First the choice of one color = 4/8. With the 7 remaining socks, the choice of the other color = 4/7. With 3 remaining of each color in the 6 socks left, P = 3/6.
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
4/8 * 4/7 * 3/6 = ?
