The entries in a two-by-two determinant $open vertical bar table row cell a blank b end cell row cell c blank d end cell end table close vertical bar$ are integers that are chosen randomly and independently, and, for each entry, the probability that the entry is odd is p. If the probability that the value of the determinant is even is 1/ 2, then the value of p, is
