A bag contains 12 red balls and 10 blue balls. A ball is drawn at random. The probability that ball drawn is red is
12/22 = 6/11
To find the probability of drawing a red ball, you need to divide the number of red balls by the total number of balls:
Probability of drawing a red ball = Number of red balls / Total number of balls
In this case, the number of red balls is 12 and the total number of balls is 12 + 10 = 22.
Probability of drawing a red ball = 12 / 22
Simplifying this fraction gives:
Probability of drawing a red ball = 6 / 11
So, the probability of drawing a red ball is 6/11.
