Suppose you roll a number cube. What is the theoretical probability of rolling a 2
Answer: \(\dfrac{1}{6}\)
Step-by-step explanation:
We know that a cube has six faces , if we roll a cube then we have chances to roll six different faces with six different number if it is not biased.
Let the number on cube be 1,2,3,4,5,6.
Thus total outcomes = 6
Then the theoretical probability of rolling a 2 is given by :-
\(P(2)=\dfrac{\text{favorable outcome}}{\text{total outcomes}}\\\\\Rightarrow\ P(2)=\dfrac{1}{6}\)
