At a track meet, 50 people ran the 100meter 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?

Best ResponseYou've already chosen the best response.1Well....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.

Best ResponseYou've already chosen the best response.1Just do it for all the finish times, yes. Assuming Im interpretting the question correctly, yeah.

Best ResponseYou've already chosen the best response.1I see. Its just called that, it doesnt really have anything to do with what we think of in geometry. Just looked it up, lol.

Best ResponseYou've already chosen the best response.0Your probabilities should add up to 1. Did you check?
