Lime Green Socks

Having established the probability of picking a matching pair of socks, now ask the group to calculate the probability of randomly picking the green pair of socks out of the bags. Kids who have used the grid approach will very quickly be able to determine that there are two outcomes of the twelve which result in the green pair of socks being chosen, so the probability of this is 2 in 12, which simplifies to 1 in 6. Those who have used the logical short cut approach for the earlier calculation will find that things become a little more complex.
