So six out of 64 will only have one uppercase letter. And finally, just like there's a one out of 64 possibility of having all uppercase letters, there's a one in 64 possibility of having no uppercase letters. And if we plot this, if we create a bar graph of this distribution, we get a normal distribution. So we basically get this normal distribution that looks like a bell curve. And so we have one out of 64 chance that six of them are uppercase and one out of 64 that none of them are uppercase. Six out of 64 gives us the likelihood that five will be uppercase and six out of 64 gives likelihood that only one will be uppercase.
