A bag contains 4 white balls and some red balls. If the probability of drawing a white ball from the bag is 2/5, find the number of red balls in the bag.
Dear student
solution to your asked query is :
let the number of the red ball be x.
the total number of balls = 6+x.
the probability of drawing a white ball is 2/5.
therefore:
thus the number of red balls is 9

hope this helps you.
