There are 5 red balls,6 white balls and 7 green balls in a box.If one ball is taken without looking,what is the probability that it is white?
prob = 6/18 = 1/3
To find the probability of drawing a white ball, we need to determine the total number of balls in the box and the number of white balls.
In this case, there are a total of 5 red balls, 6 white balls, and 7 green balls, making a total of 18 balls.
The probability of drawing a white ball can be calculated by dividing the number of white balls by the total number of balls:
Probability of drawing a white ball = Number of white balls / Total number of balls
Probability of drawing a white ball = 6 / 18
Simplifying the fraction, we have:
Probability of drawing a white ball = 1 / 3
Therefore, the probability of drawing a white ball is 1/3.
