Marna runs at the track each Monday, Wednesday, and Friday. Each day that she ran, she recorded the number of people that were at the track. Below are her results for observations on four Mondays, three Wednesdays, and three Fridays. The first Monday she saw 3 people, the next Monday she saw 7 people, the next she saw 3 people, etc. Match each scenario with the experimental probability that it will occur.

There are 10 choices, so I would match up each to see %, and figure it out that way.

OpenStudy (konradzuse):

If you look at the days the most active would be more than 4 people imo. so I would go with 7,8,5,6 40% Less than 2 would be only 1 person so that should be 10% No more than 3 people would be 3,3,2,2,1 50% At least 7 people 7,8 20%

Hope this helps.

If at least 7 people do that than what is the answer to my problem??

OpenStudy (konradzuse):

20%.

OpenStudy (konradzuse):

it's a mix and match so you need to match up the probability.

OpenStudy (konradzuse):

Since you have 10 people you need to just think it through as I did above.

Which are matched with what??? ABCD???

OpenStudy (konradzuse):

That's what it's asking...

OpenStudy (konradzuse):

First one is A, second one is D, third is B, forth is C.

I know that i just dont know what the answers are i understand it i just cant process the matching part through my head idk what the answers go with???

OpenStudy (anonymous):

?

OpenStudy (konradzuse):

Okay I'll explain it again.. you have 10 choices, each are worth 10% if you do 100%/10 people = 10%.

OpenStudy (konradzuse):

more than 4 people are 7,8,5,6 since there are 4 choices it's 40% Less than 2 would be only 1 person so that should be 10% No more than 3 people would be 3,3,2,2,1 50% At least 7 people 7,8 20% Understand?

OpenStudy (anonymous):
