1 over 15
There are 2 O's out of a total of 6 letters in the bag. The probability of drawing an O on the first draw is 2/6, which simplifies to 1/3. Since the first piece is not replaced, there are now 5 pieces of paper in the bag, with 1 O remaining. Therefore, the probability of drawing an O on the second draw is 1/5.
To find the probability of both events happening, we multiply the probabilities together:
(1/3) * (1/5) = 1/15
Therefore, the probability that Krishna draws an O twice is 1 over 15.
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 118 1 over 18 115 1 over 15 215 2 over 15 136
