Question

A student kept track of the prizes won in a contest over several months.

What is the probability that someone who won a prize won an audio player in this contest?



A.
The experimental probability is 0.8%.

B.
The experimental probability is 8%.

C.
The theoretical probability is 0.8%.

D.
The theoretical probability is 8%.

Answer 2

It is like we need a total amount of those who were in the contest, which the chart or problem fails to do

Answer 3

hmmm..

Answer 4

The answer is a.

Answer 5

Answer 7

hmm.. im trying to solve it XD

Answer 8

Yes, it is either A or C. I did 125 + 33 + 78 + 2 = 238

There are 2 people who won the Audio Player, so 2/238.

2/238 as a percent is 0.840336134453782% (A.K.A.: 0.8)

So, all we need to know, is it experimental or theoretical?

Answer 9

Oh I see, you divided 2 by 238. Yeah, you're correct.

Answer 10

yep! :3 So is it experimental probability or theoretical?

Answer 11

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.

Theoretical Probability of an event is the number of ways that the event can occur, divided by the total number of outcomes. It is finding the probability of events that come from a sample space of known equally likely outcomes.

Answer 12

Looks like a theory I believe?

Answer 13

Yes! Thank you!

Answer 14

You did the work! Glad you got it!

Answer 15

haha, thank you :3
