Bag has 4 green marbles 3 red marbles and 3 yellow marbles what is the probability that you pick a green marble do not replace it and pick another green marble

4+3+3 = 10 total marbles

4 are green so 4/10, reduced to 2/5 of picking a green one first.

 without replacing it, there would be 9 marbles and 3 green ( assuming he picked a green one first)

 so 3/9 reduced to 1/3 that the 2nd one would be green

2/5 x 1/3 = 2/15 probability of picking 2 green marbles

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
