A student has a bag of marbles.There are 5 pink 7 red 12 green 2 blue 4 black marbles in the bag.Calculate thee thee veretical probability of picking a green marble
Total number of marbles in the bag = 5 (pink) + 7 (red) + 12 (green) + 2 (blue) + 4 (black) = 30
Number of green marbles = 12
Vertical probability of picking a green marble = Number of green marbles / Total number of marbles
= 12 / 30
= 2 / 5
= 0.4
Therefore, the vertical probability of picking a green marble from the bag is 0.4 or 40%.
