What is the chance of rollin a 4 with a single die three in a row

The chance of rolling a four with a single dice in three attempts is 1/18

Step-by-step explanation:

The reason for this is there are six sides on a dice. Therefore if you were rolling it one time you'd have a one-in-six chance since there is one four in the six sides. To get the chance for three roles you'd just multiply your probability for one role by the number of roles and it would give you 1/18.

I hope this helps!:)

2.56 is the width of the garden

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
