You have 9 gymnasts and want to make a team of 4. Say one out of the nine is chosen; eight are left. Take one, then seven, and two more can be chosen. Keep doing this and your team is full. So, it's 9*8*7*6 which equals 3,024, since order doesn't matter.

Answer:
c = -18
Step-by-step explanation:
We need to distribute the -3 to each term within the parentheses. This essentially means finding the sum of the product of -3 with each of those inner terms:
-3 * c + (-3) * 14 + 3 = 15
-3c - 42 + 3 = 15
-3c = 15 + 42 - 3 = 54
c = 54/(-3) = -18
c = -18
The answer is 1/10.
There are in total 20 marbles in the bag:
3 green + 2 yellow + 6 blue + 9 red = 20 marbles
There are 2 yellow marbles of total 20 marbles. 2 of 20 can be expressed as:
2/20 = 1/10.
Therefore, <span>the probability of picking a yellow marble from the bag is 1/10.</span>
