Question

The faces of a tetrahedron die are numbered 1 to 4. If each of the 4 sides is equally likely to land down, what is the probability that the 2 does not end up face down?

1/4
3/4
1

Answer 1

3/4th would be the answer

Answer 2

The probability that 2 will land face down is 1/4 (one 2/4 possibilities)
So to find out not a 2 you would take 1 - 1/4 = 3/4 B
