Answer:
Total no of balls =7+5+3=15 After adding two blue balls=15+2=17
Red balls-7 but 3 are painted blue then
Red balls =7-3=4 Probability = 4/17
Total blue balls = 2+3=5
Probability = 5/17

Answer:
Step-by-step explanation:
P(Red)=7 P(Yellow)=5 P(Green)=3
∴the probability of obtaining red ball=7/15
P(Red)=4[∵first there is 7 red is ball & then 3 red balls painted blue , So 7-3=4]
P(Blue)=5[∵3 red ball painted blue & 2 blue ball is added]
P(Green)=3
P(Yellow)=5
∴the probability of obtaining blue ball =5/17
