So first you take 7/250*x/10000 and you cross multiply. Then you get
70000=250x
and the answer is
x=280
I hope this helps!!!!!!!
Step-by-step explanation:

If you roll two fair dice, a green one and a red one?
A= are the outcomes on the dice independent?
B= Find P(1 on green die and 2 on red die)
C= Find P(2 on green die and 1 on red die)
D= Find P(1 on green die and 2 on red die) or (2 on green die and 1 on red die)
A= yes
B= p(1)*(p2)=1/6*1/6=1/36
C= p(2)*(p1)=1/36
D= 1/36=1/18 I hope it helps !
