What is Probability?

Probability helps us to know the chances of an event occurring.

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

Given the bag has 3 red marbles, 2 blue, 4 green and 1 yellow. Therefore, the total number of marbles in the bag is 10. Now, the probability of pulling a red marble will be,

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

$\rm Probability=\dfrac{\text{Number of red marbles}}{\text{Total number of marbles}}$

Probability = 3 /10 = 0.3 = 30%

Hence, the probability of pulling a red marble is 3/10 or 0.3 or 30%.
