Probability 3322

We have the numbers 4, 6, 8, 10, and 12. What is the probability that with a randomly selected triangle, these will be the lengths of the sides of a scalene triangle?

Correct 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
