Question

HELP! What is the probability of randomly picking a green marble from a bag of 10 green marbles, 10 yellow marbles, and 5 red marbles?

Answer 1

2/5

Explanation:

For probability, it's the

number of the type you want

_______________________

the total number of items

So the equation for this would be

10/10+10+5

= 10/25

= 2/5

The final answer is 2/5. Keep in mind that probability is a ratio of likeliness between things, so you CANNOT write it as a decimal!

I hope this helped! :D
