There are5 red balls6 white balls,7 green balls in a box.without looking at it you pick one ball,what is the probabikity that it is whit?
6/18 = 1/3
1/3
To calculate the probability of picking a white ball without looking at the box, you need to know the total number of balls and the number of white balls in the box.
In this case, there are 5 red balls, 6 white balls, and 7 green balls. The total number of balls in the box is the sum of those three numbers: 5 + 6 + 7 = 18.
Now, since you want to find the probability of picking a white ball, you need to determine the number of white balls in relation to the total number of balls. There are 6 white balls out of the total 18 balls.
Finally, to calculate the probability, you divide the number of white balls by the total number of balls: 6/18 = 1/3.
Therefore, the probability of picking a white ball is 1/3, or approximately 0.33 (33%).
