What is Probability?

The probability helps us to know the chances of an event occurring.

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

Given that the jar contains 2 pink, 6 red, and 4 blue marbles. Therefore, the probability that the marble you pick will be red or blue can be written as,

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

$\rm Probability = \dfrac{\text{Number of red and blue marbles}}{\text{Total number of marbles}}\\\\\rm Probability = \dfrac{6+4}{12} = \dfrac{10}{12} = 0.8333$

Thus, the probability that the marble you pick will be red or blue is 0.8334.
