A bag contains 4 white, 2 black, 3 yellow and 3 red balls. What is the probability of getting a white or red ball at random in a single draw of one?

A.

19%

B.

58.3%

C.

12%

D.

13%

 

Answer : B

Explanation :

The probability of getting one white ball

= 4/12

The probability of getting one red ball

= 3/12

The probability of getting one white or red ball

= 4/12 + 3/12

7/12 or 7/12 x 100

= 58.3%

Hence the answer is (b).
