Aplayer rolls two dice. they lose with a sum if 2,3, or 12. what is the probability of losing on the first roll?

Step-by-step explanation:

There is 1 possibility of getting a sum of 2 → (1 + 1)

There are 2 possibilities of rolling a 3 → (1 + 2  and   2 + 1)

There is 1 possibility of rolling a 12 → ( 6 + 6)

There are 36 total number of possible outcomes.

Consider that success for this problem is rolling a 2, 3, or 12:

- "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."

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
