Question

Experimental probability

Answer 1

85%

Explanation:

Let’s identify all the outcomes less than 10, that would be 2-9

The number of times the die was rolled is obtainable by adding all the frequencies ;

That would be ;

3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 + 9 + 5 + 1 = 100

Now let’s add the frequencies of results which are less than 10;

That would be the frequencies of the numbers 2-9;

Thus, we have;

3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 = 85

The required probability of rolling a number less than 10 = 85/100 = 0.85 which to the nearest percent is 85%
