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
