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 - 38%
Experimental - 33.3%

B.
Theoretical - 33.3%
Experimental - 19%

C.
Theoretical - 16.7%
Experimental - 19%

D.
Theoretical - 33.3%
Experimental - 38%

Answer 2

`What is the theoretical probability of the spinner stopping on 2? `
there are \(\LARGE \color{green}{3}\) sections total. In this case, \(\LARGE \color{red}{1}\) of them is labeled "2"

divide the values
\[\Large \frac{\color{red}{\text{number of sections labeled '2'}}}{\color{green}{\text{number of sections total}}}=\frac{\color{red}{1}}{\color{green}{3}} \approx 0.333 \approx 33.3\%\]

Answer 3

For the experimental probability, you'll divide

(number of times a "2" comes up)/(number of spins total)

Answer 4

Woow

Answer 5

okay, so 19/50?

Answer 6

yep 19/50 = 0.38 = 38%

Answer 7

Oh! Okay! Thank you!

Answer 8

or you can think of it as

19/50 = 38/100 ... multiply top and bottom by 2

38/100 = 38%

Answer 9

you're welcome
