A bag contains 2 red balls,3blue ballsand 10 green balls, ahad draws 2 balls out of the bag .What is the probaaility that he gets a green ball and a blue ball

1/7

Step-by-step explanation:

The bag contains 2 red balls, 3 blue balls and 10 green balls.

The total number of balls in the bag is:

2 + 3 + 10 = 15 balls

The probability of picking a green ball is:

10/15 = 2/3

There are now 14 balls left in the bag.

The probability of picking a blue ball is:

3/14

Therefore, the probability of picking a green ball and a blue ball is:

2/3 * 3/14 = 2/14 = 1/7

thats not a system of equations, that is a solution

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
