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 =[tex]\frac{25}{40}=\frac{5}{8}[/tex]

In 400 trials , the number of green marbles should expect =[tex]\frac{5}{8}\times400=250[/tex]

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