Question

fred rolled a number cube (die) 20 times. the results of his experiment are shown below.

number	1	2	3	4	5	6

select the experimental probability of rolling an even number based on fred’s experiment.

$\frac{3}{10}$ $\frac{7}{20}$ $\frac{4}{5}$ $\frac{7}{10}$

Explanation:

Step1: Identify even numbers on die

Even numbers on a die are 2, 4, 6.

Step2: Find total times even numbers rolled

For 2: 4 times, 4: 6 times, 6: 4 times. Sum: \(4 + 6 + 4 = 14\).

Step3: Total rolls

Total rolls = 20 (given).

Step4: Calculate experimental probability

Experimental probability = \(\frac{\text{Times even rolled}}{\text{Total rolls}} = \frac{14}{20} = \frac{7}{10}\).

Answer:

\(\frac{7}{10}\)
