Question

A standard number cube is tossed. Find the probability of getting P(6 or even).A.1/2B.1/3C.2/3D.4

Answer 1

A standard number cube is a fair-die.

The sample space for a die is six (6).

`S=\mleft\lbrace1,2,3,4,5,6\mright\rbrace`

The probability of an event, E , is defined mathematically as:

`Pr(E)=\frac{\text{number of favourable outcome}}{\text{number of sample space}}`

To obtain the probability of getting a 6 or an even number, we have:

`\begin{gathered} Pr(6\text{ or even)=}(1)/(6)+(3)/(6) \\ Pr(6\text{ or even)=}(4)/(6) \\ Pr(6\text{ or even)=}(2)/(3) \end{gathered}`

Hence, the correct option is option C
