A bag contains 40 marbles, 4 of which are blue, 10 are red, 25 are green, and 1 is purple. Shawna takes a marble out of the bag, records the color, and returns it to the bag. How many green marbles should she expect after 400 trials?

the bag contains 40 marbles, not 100.
25 = 5/8 are green, so in 400 draws, she should expect 5/8 * 400 = 250 green marbles.
You are correct. I apologize for the mistake in my previous response.
Given that 5/8 of the marbles are green, Shawna should expect to get 5/8 * 400 = 250 green marbles after 400 trials. Thank you for pointing out the error.
100
After 400 trials, Shawna can expect to get 25% green marbles (25 out of 100) based on the initial distribution of marbles in the bag. So, after 400 trials, Shawna should expect to get 100 green marbles.
