­A box contains exactly 40 bottles, each of which contains only one of three types of soda—orange, lemon, and ginger. What is the probability of randomly selecting a ginger soda, without any replacement in the box, on each of 3 consecutive attempts?

(1) The number of orange sodas is 5 more than the number of ginger sodas.

(2) The number of ginger sodas is 10 more than the number of lemon sodas.­
­given
O+G+L=40
target g/ 40

#1
The number of orange sodas is 5 more than the number of ginger sodas.
L+2g=35
insuffcient
#2
The number of ginger sodas is 10 more than the number of lemon sodas.­
G=10+L
O is not known insufficient
from 1 &2
G-10+2G=35
G=15
15/40 ; 3/8
sufficient
option C
I understand you don't need to fully solve this but the total probability would be 15/40 * 14/39* 13/38 correct?
