Consider a baseball world series (best of 7 game series) in which team a theoretically has a 0.55 chance of winning each game against team b. simulate the probability that team a would win a world series against team b by simulating 1000 world series. you many use any software to conduct the simulation.

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.
