At the local playground, there are six different swings, three different spring riders and four different slides. Suppose that a toddler just arrives at the playground and selects two pieces of playground equipment "without replacement" (so, just as an example, if the toddler chooses a swing first, they can then choose a different swing or a different type of equipment, but not the exact same swing). Find the probability that the toddler selects a slide first and then a spring rider.
