7+3 = 10 total marbles
1st pick = 7/10 for a red one
2nd pick = 6/9 reduces to 2/3 for a red one
3rd pick = 3/8 for a white one
7/10 x 2/3 =14/30 reduces to 7/15
7/15 x 3/8 = 21/120 reduces to 7/40
probability = 7/40
V=1/3(6)(4)(8) this is the correct answer
3/20 is the answer in simplest form
The median of the given data is nine!!
D.) x = 5, because when you plug five in for x, 5 + 5 = 10 is correct.
