Answer:
The required probability is 0.1. 
Step-by-step explanation:
red balls = 3 
yellow balls =  2 
blue balls = 5 
Selected balls = 5 
Number of elemnets in sample space = 10 C 5 = 1260
Ways to choose 1 red ball and 4 other colours =  (3 C 1 ) x (7 C 4) = 105 
Ways to choose 5 balls of other colours = 7 C 5 = 21
So, the probability is
