SOLUTION: In a basket of 50 apples, the probability of it having all at good quality is 0.35, while the probability of it having 1, 2, 3, 4 bad apples are 0.25, 0.2, 0.18, 0.02 respectively.

Question 1121566: In a basket of 50 apples, the probability of it having all at good quality is 0.35, while the probability of it having 1, 2, 3, 4 bad apples are 0.25, 0.2, 0.18, 0.02 respectively. Now if we randomly choose 10 apples and find out there is one bad apple. What is the probability of no more than 2 bad apples in the basket?

No more than 2 bad apples in a basket means no chance for 3 apples (0.18 probability) or 4 apples (0.02 probability). The probability of no more than 2 apples is the complement of 0.20 or 0.80, the same result as adding the probability of 0, 1, and 2.
