At a track meet, 50 people ran the 100-meter dash. 2 people finished in 11 seconds, 5 people finished in 12 seconds, 8 people finished in 13 seconds, 10 people finished in 14 seconds, 21 people finished in 15 seconds, 2 people finished in 16 seconds, and 2 people finished in 17 seconds. What is the probability distribution for the finish times?

Question

I know i can to id buy putting it in my TI but im kinda confused.

psymon · Answer

Well....each finish time has its own probability. Probability is (success/possibilities). So for our first time of 11 seconds. We have 50 runners, so 50 possibilities. We have 2 "successes" for 11 seconds, therefore thatprobability is 2/50. Just do the same thing with each finish result.

So... Thats it?

psymon · Answer

Just do it for all the finish times, yes. Assuming Im interpretting the question correctly, yeah.

Its geometry bud...

psymon · Answer

How is this geometry? O.o

@Directrix Can you help?

anonymous · Answer

I dont know man, thats what i am trying to figure out!

psymon · Answer

Its a statistics question xD

anonymous · Answer

but it was in my geometry lesson...

psymon · Answer

Dunno how. But this is a typical stats question.

anonymous · Answer

Weird...

Geometric Probability Distributions

psymon · Answer

I see. Its just called that, it doesnt really have anything to do with what we think of in geometry. Just looked it up, lol.
