Amelie has a spinner divided into ninths equal sections that are labeled 1 through 9. she wants to compare the theoretical proba
VMariaS [17]

The theoretical probability =\dfrac{5}{9},  The experimental probability  = \dfrac{5}{12}

<h3>What is experimental probability?</h3>

The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.

The sample will be ={1,2,3,4,5,6,7,8,9}=9

favourable outcomes={1,3,5,7,9,}=5

The theoretical probability of spinning and odd number = \dfrac{5}{9}

As she spends the spinner 12 times

The experimental probability = \dfrac{5}{12}

Hence the theoretical probability =\dfrac{5}{9},  The experimental probability  = \dfrac{5}{12}

Answer:

76/11 ; 7.32 ; 7.546 ; 151/20

Step-by-step explanation:

Given data:

The numbers are listed as below

The numbers are written in the same format that is in decimal form

7.55 ; 6.90901 ; 7.32 ; 7.546

Arranging the numbers starting with the least number

6.90901 ; 7.32 ; 7.546 ; 7.55

76/11 ; 7.32 ; 7.546 ; 151/20

Please note the value of 151/20 is exactly 7.550 which makes it larger than 7.546.
