Answer 1

Answer: A. 1/2
-------------------------------------------------
The total number of balls is 12.

The total number of balls is 21.

The probability of selecting the blue ball:

P(blue)= 3/20
-
The probability of selecting the yellow ball:

P(yellow)=5/12
------------------------------------------------------------------------
P(yellow)+ P(blue) = 1/2

AWNSER = (1/2)
