Answer:
2/15
Step-by-step explanation:
There is a 4/10 probability that she chooses blue the first time, but the second time it is a 3/9 chance because she didn't put the marble back so there are 9 marbles in total, 3 blue ones.
4/10 x 3/9 = 2/5 x 1/3 = 2/15
I hope this helps :)

5/8 = 2/3 the entire box
Half of 2/3 is 1/3, and 2/3 + 1/3 = 1
So find half of 5/8 and add it to 5/8.
5/8 * 1/2 = 5/16
5/8 + 5/16
Change 5/8 to a fraction with a denominator of 16:
10/16 + 5/16 = 15/16
So the original weight is 15/16 pounds.
