Question

What is the probability of picking a blue or yellow ball from a bag containing three yellow, four green, two blue, and one orange ball?

(A) 3/10
(B) 1/5
(C) 3/8
(D) 2/5

Answer 1

The probability of picking a blue or yellow ball from the bag is 2/5. Hence the correct answer is option D

Step-by-step explanation:

To find the probability of picking a blue or yellow ball from the bag, we need to calculate the number of favorable outcomes and divide it by the total number of possible outcomes. In this case, the number of blue balls is 2 and the number of yellow balls is 3, making a total of 5 favorable outcomes. The total number of balls in the bag is 3 + 4 + 2 + 1 = 10. Therefore, the probability of picking a blue or yellow ball is 5/10, which simplifies to 1/2.

So, the correct answer is option (D) 2/5.
