Question

A spinner has three congruent sections numbered 1, 2, 3. Yolanda made 50 spins of this spinner and recorded the outcomes in this table.

Outcome Number
1 15
2 19
3 16

What is the theoretical probability of the spinner stopping on 2? What is the experimental probability of the spinner stopping on 2?

A.
Theoretical - 33.3%
Experimental - 19%

B.
Theoretical - 33.3%
Experimental - 38%

C.
Theoretical - 38%
Experimental - 33.3%

D.
Theoretical - 16.7%
Experimental - 19%

Answer 1

i will fan and medal

Answer 3

pls help

Answer 4

Theoretical is the percent that you expect the spinner to land on 2. Experimental is the amount it actually did

Answer 5

theoretical = # of sections with 2/ total number of sections

Answer 6

so im still confused what are the steps to get thae answer for theritcal

Answer 7

I'll walk you through it. How many sections are there on the spinner?

Answer 8

thanks 3 sections

Answer 9

Ok. and how many of them are numbered 2?

Answer 10

19

Answer 11

not quite. A picture always helps

Answer 12

Out of the 3 sections, only 1 of them has 2 on it. Does that make sense?

Answer 13

oh yeah i get that

Answer 14

So the theoretical probability is 1/3 since 1 of the 3 spaces has "2"

Answer 15

ok i understand that

Answer 16

Great. For experimental, they spun 50 times. The table is saying that it landed on "1" 15 times, landed on "2" 19 times, and landed on "3" 16 times

Answer 17

Experimental = # of spins that landed on 2 / total number of spins

Answer 18

so 2/3

Answer 19

is that right

Answer 20

19 spins out of 50 landed on "2". How would you write that as a fraction?

Answer 21

or percent

Answer 22

i got to go but i tbhing i understand thanks
