Out of jar with 100 marbles, 49 are blue marbles, 7 are green marbles, 27 are red marbles and 17 are yellow marbles. What is the probability of drawing a red marble?
27/100 = .27
Post.
27/100
To calculate the probability of drawing a red marble, we need to determine the number of red marbles and then divide it by the total number of marbles in the jar.
In this case, there are 27 red marbles out of a total of 100 marbles.
So, the probability of drawing a red marble can be calculated as follows:
Probability of drawing a red marble = Number of red marbles / Total number of marbles
= 27 / 100
= 0.27 or 27%
Therefore, the probability of drawing a red marble is 0.27 or 27%.
