Julia made a die for a game. It had 5 faces, labeled 1-5. Because of the shape of the die, it was biased in favor of rolling a 3. We do not know the amount of bias. She experimented to estimate how likely it was for a 3 to be rolled and her results are in the above table.Using her experimental results find the best estimate of the probability of rolling a 3.

Solution

Solution

\frac{1}{6}

Solution steps

The possible outcomes when \mathrm{a die is rolled} is

{1, 2, 3, 4, 5, 6} .

Therefore, the number of possible outcomes:

6

The number of favorable outcomes of \mathrm{rolling a 3}:

1

Probability

= \frac{number of favorable outcomes}{total number of outcomes}

= \frac{1}{6}
