Question

3 POINSSSSSS

The bar graph shows the results of rolling a number cube (a die) 50 times. What is the probability of rolling an odd number? How does this compare with the theoretical probability of rolling an odd number?

Experimental Probability. Theoretical Probability

P(odd) = % P(odd) = %

Answer 1

yes

Explanation:

Answer 2

see below

Explanation:

Experimental means what actually happened

P(odd) = (number of 1 + number of 3 + number of 5) / total

= (10+8+8) / 50

= 26/50

= 13/25 = 52%

Theoretical means what we expect to happen

P (odd) = (number of 1 + number of 3 + number of 5) / total

=(1+1+1)/6

=1/2 = 50%

We rolled an odd just a little more than the expected amount of times
