Answer:
125
Step-by-step explanation:
To find the expected number of black marbles, take the probability of getting a black marble times the number of marbles drawn
P(black) * 200
5/8 *200
125
We should expect 125 black marbles
Answer:
125
Step-by-step explanation:
Once you have the theoretical probability of picking a black marble which is 5/8, just multiply the number of drawings by 5/8 to get the answer to problem 8.
200 * 5/8 = 1000/8 = 125
