Probability of Picking Three White Balls
Step 1: Find the total number of possible ways to pick three balls out of 15.
Total ways = 15C3 = (15*14*13)/(3*2*1) = 455
Step 2: Find the number of ways to pick three white balls out of six.
Ways to pick three white balls = 6C3 = (6*5*4)/(3*2*1) = 20
Step 3: Find the probability of picking three white balls.
Probability = Ways to pick three white balls / Total ways
Probability = 20/455
Probability = 4/91
Therefore, the probability of picking three white balls out of the basket is 4/91 or option (a).
