There are 3 ants in the 3 positions of a corners of a triangle.Then what is the probability to intersect the ants when they move in the direction like that triangle.
Read Solution (Total 2)
-
- An ant can go Left or Right. There are 8 different combinations:
1.LLL
2.RRR
3.RRL
4.RLR
5.LRR
6.RLL
7.LRL
8.LLR
to intersect they are 6 ways(except LLL and RRR) therefore probability to intersect is 6/8 i.e 75% - 10 years agoHelpfull: Yes(23) No(1)
- =3/4(75%)
- 10 years agoHelpfull: Yes(2) No(1)
