PLS HELP!! A student randomly guesses the answers to two true-false questions. Describe and correct the error in finding the pro
bability of the student guessing both answers correctly. The student can either guess two incorrect answers, two correct answers, or one of each. So the probability of guessing both answers correctly is 1/3
The student was wrong. The probability is actually 1/4.
Step-by-step explanation:
Let's say you have question A and question B. You could have incorrect on A, and incorrect on B. Or, you could have incorrect on A, but a correct on B. Or, you could have an incorrect on B, but a correct on A. Or, both could be correct. <em><u>Since there are 4 different possibilities, the actual probability is 1/4.</u></em>
