permutations in baseball

Hello,

How many permutations are there of the letters in the word baseball? How many begin with the letter a?

I got the first part, just not the second.
First Part: 8!/( 2!*2!*2!)= 40320/8= 5040

thanks for the help!

If the word has to start with an "a", then you put the "a"in the first position and you have 7 letters left. The number of ways you can arrange the 7 remaining letters is the answer: 7!/(2!2!)=1260
