find the probability of picking two green marbles when 2 marbles are picked from the bag containing 11 green and 8 blue marbles

11/19 chance

OR

roughly 57% chance.

Step-by-step explanation:

If we add our marbles, we have a total of 19 marbles to pick from. 11 of those marbles are green. This means we have a 11/19 chance of picking two green marbles.

If you want to find the percentage then do this:

We know that we have a 11/19 chance. To find the percentage, we would need to turn the fraction into a decimal first.

11÷19≈0.579

To turn a decimal into a percentage, we would need to multiply the decimal by 10 (move the decimal two spaces to the right.)

That would give us 57.9%.

So, you have, approximately, a 57% chance of picking two green marbles.

probably .5

i can on others if necessary.
