john rolled a six sided die with the following results:
frequency table of dice
outcomes
what was the mean of the dice outcomes based on the frequencies given? round your answer to two decimal places.
your answer:
answer

Explanation:

Step1: Calculate the sum of (dice outcome × frequency)

$$1\times12 + 2\times13+3\times12 + 4\times9+5\times9+6\times11$$
$$=12+26 + 36+36+45+66$$
$$=221$$

Step2: Calculate the total frequency

$$12 + 13+12 + 9+9+11$$
$$=66$$

Step3: Calculate the mean

The mean formula is $\frac{\text{sum of (dice outcome × frequency)}}{\text{total frequency}}$. So, $\frac{221}{66}\approx3.35$

Answer:

$3.35$
