To identify:The theoretical probability of getting a 1 or 6 when rolling a standard number cube?
The probability is
Given information:
The given is A standard cube is tossed. Since there are six faces numbered as 1, 2, 3, 4, 5, and 6.
Explanation:
Consider the information.
A standard cube is tossed. Since there are six faces numbered as 1, 2, 3, 4, 5, and 6.
So
As 1 exists one time on dice, so probability of getting 1 is
Also, as 6 exists one time on dice, so probability of getting 6 is
These both are mutually exclusive events.
For mutually exclusive events A and B
Therefore
Substituting all value in equation (1) and solve.
Hence
