It is an 8/15 probability. there are 15 marbles total (5y+7p+3pl=15) 

5/15y, 7/15p, 3/15.

5/15+3/15= 8/15

andriy [413]
Given that the population has been modeled by the formula:
a=118e^(0.024t), the time taken for the population to hit 140k will be given by:
140000=118e^(0.024t)
solving for t we shall have:
140000/118=e^(0.024t)
thus;
0.024t=ln(140000/118)
t=1/0.024*ln(140000/118)
t=295
thus the time the population will be 140000 will be:
1998+295
=2293

to find the length, divide the area by the width
480/12= 40
