## anonymous one year ago WILL MEDAL AND FAN NO LIE Cards numbered 1, 1, 2, 3, 4, 4, 4, 5, 6, 6, 7, 8, 8, 8, and 9 are placed in a bag. If a card is drawn from the bag and then replaced 135 times, about how many times would a 6 be drawn? A. 2 B. 9 C. 15 D. 18

1. Vocaloid

(number of 6's/total number of cards)*135

As Vocaloid wrote $\Large \text{Expected Number of 6's} = \frac{\text{Number of 6's}}{\text{Total number of cards}}*135$ $\Large \text{Expected Number of 6's} = \frac{2}{15}*135$ $\Large \text{Expected Number of 6's} = ???$
