Question

Which is an example of theoretical probability?
A. Raul has a batting average of .333 so he should get a hit 1 out of every 3 at bats.
B. You flipped a coin 100 times and got "tails" 70 times. The probability of getting "tails" on your next flip is 70%
C. Prior to conducting an experiment on rolling a die, you determine the probability of rolling a 5 at 1:6
D. You roll a die 10 times and get a result of 5 three times. You determine that there is a 30% of rolling a 5 on the next roll

Answer 1

Answer 2

B right?

Answer 3

I am thinking B is not correct because it involves experimentation and not the theory.

Answer 4

so what do u think ?

Answer 5

Is this "f rolling a 5 at 1:6" supposed to read "rolling a 5 is 1:6" ? Is, rather than "at."

Answer 6

I ask that because the theoretical probability of tossing a 5 is 1/6.

There is one way to get a "5" and 6 outcomes of the toss of a die.

Answer 7

That is the only option I see as being based on theory.

These words indicate that: Prior to conducting an experiment on rolling a die

Answer 8

@katlin95 So, which option is that?

Answer 9

one sec

Answer 10

Okay

Answer 11

im assuming it may be D

Answer 12

Not D. That is because the option begins with the person rolling a die and doing an experiment.

"You roll a die 10 times and get a result of 5 three times"

Answer 13

Which option begins "Prior to rolling a die...." That means the person is using theoretical probability.

Answer 14

then it has to be C! lol

Answer 15

That is what I got.
