a chimp is taking a multiple-choice test. of course the chimp can't read and is guessing for every question. if there are 4 choi
ces for each question, and there are 84 questions on the test, how many questions can we expect the chimp to answer correctly? (hint: there is a 25% chance that the chimp will guess correctly)
First, subtract 63 from 75 to find out how much it decreased. 75 - 63 = 12 Divide 12 by 75. 12 / 75 = 0.16 In percents, that is 16%. He spent 16% less this month. Hope this helps!
