A box contains 25 red balls and 5 white balls.what is the probability of picking a red ball

The probability of picking a red ball can be calculated by dividing the number of red balls by the total number of balls in the box.

Number of red balls = 25
Total number of balls = 25 (red balls) + 5 (white balls) = 30

Probability of picking a red ball = 25/30 = 5/6 = 0.8333 or 83.33%
