Answer:
5
Step-by-step explanation:
Total no. of balls = 50
No. of white balls = 20
No. of non-white balls = 30
No. of red balls and blue balls = 1;2
1x + 2x = 30
3x = 30
x= 30/3
x = 10
So, there are 10 red and 20 blue balls
Probability of getting a red ball = 50/10
= 5
Also on the funny side, you can say that every time you pick a ball it might be red because a bucket is open so you can see which ball you are picking
