With a mean height of 143.5 centimeters, so it's a mean of 143.5 centimeters, and a standard deviation of about 7.1 centimeters, standard deviation of 7.1 centimeters, what is the probability that a randomly chosen fifth grade boy would be taller than 157.7 centimeters? Let's just draw out this distribution like we've done in a bunch of problems. So far, they're just asking us one question. So we can mark this distribution up a good bit. Let's say that's our distribution. And the mean here, the mean they told us is 143.5. They're asking us taller than 157.7.
