A ball is drawn from random from a box containing the 70 white and 30 red balls. The probability that the balls is , white, red is;
Explanation
Solution
total balls
white+red = 70+30=100
so white probability=70/100
=7/10
so red possibility = 30/100
=3/10
so to check probability then add them
=7/10+3/10
=10/10
=1
hense the answer is 1
