An ant begins at the top of the pictured octahedron. if the ant takes two "steps", what is the probability it ends up at the bottom of the octahedron? assume a "step" is a journey from one vertex to an adjacent vertex along an edge.

Explanation:

Ant has 4 ways to go at first. No matter where it goes each way has 4 more ways. So to get to the bottom from 4 ways, there is only one way so, 1/4 is the answer

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

yes.. it's proven to be 36.
