One card is drawn from a deck of 13 cards numbered 1 through 13. Find the following probabilities. (Enter your probabilities as fractions.) Find the probability that the card is even or divisible by 3.

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.
