Answer:
I think the total number of combinations of 3 from 6 = 6C3 = 20
All possible combinations of 3 which have a product divisible by 3 must contain either a 3 or a 6.
So the number not divisible must be 3 combinations from the number 1, 2, 4, and 5.= which is 4
So the required probability is 20-4 ? 20 = 16/20 = 0.8 Answer
Hope this help you! :)

Answer:
EF = 13.1
FD = 35.3
Step-by-step explanation:
The distance between two points on a number line is the positive difference between their coordinates.
EF = F - E = 19 -5.9
EF = 13.1
__
FD = F - D = 19 -(-16.3) = 19 +16.3
FD = 35.3
Answer:(2x+5)(x+5)=0
Step-by-step explanation:
2x^2+15x+25=0
Factorise we have
2x^2+10x+5x+25
(2x^2+10x)+(5x+25)=0
2x(x+5)+5(x+5)=0
(2x+5)(x+5)=0
