Step-by-step explanation:
Probability of drawing a black ball from First basket = no of black balls ÷ total number of balls
= 10÷14 = 5/7
Probability of drawing a black ball from second basket, similarly = 7/12
Since we have to find the probability of first AND second basket, we will multiply the probabilities.
Total probability
= 7/12 x 5/7 = 5/12 (Answer)
