Triangle probability

From the numbers 4, 6, 8, 10, and 12, three are chosen at random. What is the probability that the three chosen numbers can form the sides of a scalene triangle?

Final Answer:

p =  0.7

Step-by-step explanation:

C3(5)=(35)=3!(53)!5!=2154=10  n=(35)=10  4+6  10 4+6  12 4+8  12  p=13/n=13/10=0.7
