During 20 spins, a spinner landed on blue 10 times. If you spin the spinner once, what is the experimental probability that it will land on blue?
Answered by Ms. Sue
Someone has answered your other similar questions. What did you learn from them?

Answered by Anonymous
I don't know for each question whether we should for example: simplify 10/20 or add 20+30 = 50 and so simplify 10/50......

How were the other problems solved?

Answered by Anonymous
it's different for each problem apparently for some you add the total example: 20+10 = 30 put 10/30 and simplify it and on some you just for example for this problem simplify 10/20.. The thing is I don't know which rule to do when I get a question like the ones I asked

20 spins
10 land on blue

Which method will give you a reasonable fraction?

Answered by Anonymous
well 10/30 simplified would be 1/3
and 10/20 would be 1/2
I don't know what you mean by a reasonable fraction like how do you know if it's a reasonable fraction?
Answered by Ms. Sue
Both of those are reasonable answers.

10 out of 20 times = 1/2

how am I supposed to know whether 1/2 or 1/3 is the answer?
Answered by Anonymous
It certainly can't be both.
Answered by Ms. Sue
I told you the answer.
Answered by Anonymous
yes but if it's both reasonable answers.. how would you know if it's 1/2 or 1/3? why isn't it 1/3?
Answered by Ms. Sue
It's not 1/3 because the spinner was only used 20 times.
