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?
Someone has answered your other similar questions. What did you learn from them?
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?
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?
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?
Both of those are reasonable answers.
10 out of 20 times = 1/2
