1. 1/4
Step-by-step explanation:
Total number of balls be = 12
Number of red ball be = 3
Number of green ball be = 3
Number of bule ball be = 3
Number of yellow ball be = 3
Now,
P(getting of random three balls with same colour) = Number of random balls with same colour/ Total number of balls.
P(getting of random three balls with same colour) = 3/12 = 1/4.
