<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
Probability=(Desired Outcomes)/(Total Number of possible outcomes)
The total number of marbles in the bowl is 24, while it contains 6 white, 8 blue, 7 black and 3 red. Therefore, the probability of choosing a black marble from the bowl is,
P(Black marble) = Number of black marble/Number of total Marble
P(Black Marble) = 7/24 = 0.2917
Hence, the probability of choosing a black marble from the bowl is 0.2917.
