Question

Tami rolled a die 20 times. 14 times it landed on an even number; 6 times it landed on an odd number. How does the experimental and theoretical probability compare, for rolling an odd number?

A)
The theoretical probability is higher.
B)
The experimental probability is higher.
C)
The experimental and theoretical probability are equal.

Answer 1

A: "The theoretical probability is higher."

Explanation:

The theoretical probability of rolling an odd number on a die is 1/2, or 0.5. Since Tami rolled the die 20 times and it landed on an odd number 6 times, the experimental probability of rolling an odd number is 6/20, or 0.3. Since 0.3 is less than 0.5, the theoretical probability is higher. Therefore, the correct answer is option A: "The theoretical probability is higher."
