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

(1) Let's move all of components that do not contain  (our target) to the right side (notice the change of sign of
 (our target) to the right side (notice the change of sign of  from negative to positive):
 from negative to positive):

(2) Let's divide both sides of equation by 4:

(3) Now, we simplify the left side:

This is the solution.

Answer:
7 is true
Step-by-step explanation:
if y=5, then 94=130, which is false.
If y=6, then 112=130, which is false
If y=8, then 148=130, which is false.
If y =7, 130=130, which is true
