Answer:
1) 4/7
2) 3/7
Explanation:
No. of red balls= 3
No. of black balls= 4
Total no. of balls= 3+4
=7
Total possible outcomes= Total no. of balls= 7
1) Desired outcomes= No. of black balls= 4
P(getting a black ball)= Desired outcomes/Total possible outcomes= 4/7
2) Desired outcomes= No. of red balls= 3
P(getting a red ball)= Desired outcomes/Total possible outcomes= 3/7
Hope it helps :)
