Krishna puts the letters of the word SCHOOL on pieces of paper and puts the pieces in a bag. He draws two letters without looking. The first piece of paper is NOT REPLACED before the second piece is drawn. What is the probability that Krishna draws an O twice? (1 point) Responses 115 1 over 15 136 1 over 36 215 2 over 15 118
1 over 15
Explanation:
The probability of drawing an O on the first draw is 2/6 (since there are 2 O's out of 6 letters). After drawing an O on the first draw, there will be only 5 letters left in the bag with 1 O left. Therefore, the probability of drawing an O on the second draw is 1/5. Since the events are independent, the probability of drawing an O twice is (2/6) * (1/5) = 1/15.
