Which tells us that what's left over, this tail that we care about, and this left tail right here has to make up the rest of it, or 5%. So those two combined have to be 5%. And these are symmetrical. We've done this before. This is actually a little redundant from other problems we've done. But if these are combined 5% and they're the same, then each of these are 2.5%. So to the answer to the question, what is the probability that a randomly chosen fifth grade boy would be taller than 157.7 centimeters?
