Watch. It said there are 6 seniors, 4 juniors, and 3 sophmores.
So just put them in all fractions, and multiply.
2%2F6+%2A+1%2F4+%2A+1%2F3%29. and it will be 1%2F3+%2A+1%2F4+%2A+1%2F3 and it will be: 1%2F3+%2A+1%2F4=+1%2F12+%2A+1%2F3=+1%2F36. There is 1/36 chance.
-OR-
For the percentage, 1%2F36 is 27.7777777777777777777777777777...% or rounded up to 28% chance.
