Answer:
125
Step-by-step explanation:
The total number of marbles is 6+10 = 16
P (black) = black / total
= 10/16 = 5/8
With 200 draws, take the probability of P(black) times 200 since the marble is returned each time
200 * (5/8) = 125
We would expect to get 125 black marbles
Answer:
9/14

= (-3*-3)/(2*7)
= 9/14
Hence the equivalent result expressed as a fraction is 9/14
