The answer is :
b = t - 5 / 4
Try .2 and see if it works.
Answer:
1/21.
Step-by-step explanation:
There are 9 digits and the total number of permutations of 3 from 9 is 9P3
= 9!/6! = 504.
There are 4 even digits so the number of permutations of 3 from these 4 is 4! (4-3)! = 4*3*2 = 24.
So the required probability = 24/504
= 1/21.
This would be perpendicular
I wanna say it’s d because of the way it’s set up, i hope this helps if not i’m really really sorry
