Each letter in the word "mathematics" is written on a slip of paper and placed in a box. lynette chooses a letter from the box, leaves it out, then picks another letter. what's the probability that lynette chooses 2 vowels? simplify your answer.

Mathematicstotal vowels are 4...total letters are 11

probability of first pick being a vowel is : 4/11
leaving the letter out..
probability of second pick being a vowel is : 3/10

probability of both is : 4/11 * 3/10 = 12/110 reduces to 6/55 <==

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
