Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An experiment consists of rolling a fair number cube. Find the theoretical probability of rolling a 3.
A
1/6
B
3/6
C
1
D
1/2
Explanation: 

Detailed explanation-1: -Answer: Because there is only 1 number “3” on a dice with 6 sides meaning you’ll have 1/6 chance of getting a 3.

Detailed explanation-2: -A number cube is a 6 sided die, so the probability of rolling a 3 is 1/6.

Detailed explanation-3: -Experimental probability is determined by the actual results of an experiment. If a fair die is rolled 6 times and 3 is rolled 2 out of the 6 times, the experimental probability of landing on the number 3 is 2/6 or 1/3. Experimental probability is subject to change because the results of an experiment may change.

Detailed explanation-4: -So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance.

Detailed explanation-5: -Answer: The probability of rolling a sum of 6 with two dice is 5/36. Let’s solve this step by step.
