A group of freshmen at a local university consider joining the equestrian team. Thirty‑five percent of students choose Western riding, 45 % choose dressage, and 50 % choose jumping. Fifteen percent choose both dressage and jumping, while 10 % choose Western and dressage. No one chooses Western and jumping. There are no horses suitable for two styles, and each student is assigned to one horse.

If five students decide to join the team, what is the probability that at least one student joins the dressage team?

A. 0.0185
B. 0.9497
C. 0.0412
D. 0.0503

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

b) well because you get well

lo.lll

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."
