10

Step-by-step explanation:

Answer 2

Answer:

Question-

To find probability of a blue ball

Given-

Total 750 balls

Red :white:blue= 7:8:10

Solution-

Add 7+8+10= 25

• Divide each term by 25 and multiply by 750

7/25×750= 7×30= 210 ( Red balls)

8/25×750= 8×30= 240( White balls)

10/25×750= 10×30= 300 ( Blue balls)

Hence, the probability of Blue balls is 300
