hey Siri has a bag of marbles there are five pink, seven red 12 green, two blue and four black marbles in the back calculate the theoretical probability of picking a green marble
The theoretical probability of picking a green marble can be calculated by taking the number of green marbles and dividing it by the total number of marbles in the bag.
Number of green marbles = 12
Total number of marbles = 5 (pink) + 7 (red) + 12 (green) + 2 (blue) + 4 (black) = 30
Probability of picking a green marble = Number of green marbles / Total number of marbles
= 12 / 30
= 0.4
Therefore, the theoretical probability of picking a green marble is 0.4 or 40%.
