Emma conducted an experiment in which she rolled a six-sided, fair number cube 300 times. How many times would you predict she rolled a 6?

Answer 1

To predict how many times Emma rolled a 6 when rolling a six-sided fair number cube 300 times, we can use the concept of probability.

The probability of rolling a 6 on a fair six-sided die is \( \frac{1}{6} \).

To find out how many times we would expect to roll a 6 in 300 rolls, we can calculate:

\[ \text{Expected number of times rolling a 6} = \text{Total rolls} \times \text{Probability of rolling a 6} \]

\[ \text{Expected number of times rolling a 6} = 300 \times \frac{1}{6} \]

\[ = 300 \div 6 \]

\[ = 50 \]

Thus, we would predict that Emma rolled a 6 approximately 50 times.
