Question

4 normal distinguishable dice are rolled once. The number of possible outcomes in which at least one dice shows up 2?

• A. 216
• B. 648
• C. 625
• D. 671

Answer 1

The correct option is D 671

The number of possible outcomes in which atleast one dice shows up $2$ is:

$\begin{array}{c}=(6\times 6\times 6\times 6)-(5\times 5\times \times 5\times 5)\\ =1296-625=671\end{array}$

Hence, the correct option is $D$
