black | 10

ursula draws a marble from the bag randomly without looking. she then draws another marble from the bag without replacing the first one. which expression shows the probability of drawing black marbles in both the trials?

a. [ 10 over 16] + [ 9 over 16]
b. ( 10 over 16) + ( 9 over 15)
c. ( 10 over 16) * ( 9 over 16)
d. ( 10 over 16) * ( 9 over 15)
