Question #2cf30

Answer 1

`0.25`

Explanation:

experimental probability = no. of times outcome occurs / total no. of trials

number of times outcome occurs (for `3` and `6`)

`=4+6`

`=10`

total no. of trials `= 10+6+4+8+6+6`

`=40`

no. of times outcome occurs / total no. of trials

`= 10/40 = 1/4 or 0.25`

experimental probability `= 0.25`

-

NB: experimental probability does not have to be equal to theoretical probability.

with only `40` trials conducted, `0.25` does not represent the theoretical probability of a `3` or a `6` on this dice `(~0.33)`.

so if you get an answer like this in the future, it's most likely right.

and if you get a question asking whether the dice is biased because if this result, note that a much larger number of trials would be needed to prove this.
