250 because 25 is 63% of 40 and 250 is 63% of 400.

Answer: The number of green marbles should expect after 400 trials = 250

Step-by-step explanation:

Given: The total number of marbles in the bag = 40

The number of green marbles in the bag = 25

The probability or chances for choosing green marble =\(\frac{25}{40}=\frac{5}{8}\)

In 400 trials , the number of green marbles should expect =\(\frac{5}{8}\times400=250\)

Hence, the number of green marbles should expect after 400 trials = 250
