As the semiconductor is added with both type of impurities i.e. acceptor and donor type both. It is very clear that acceptor type doping is more than the donor type doping and the net effecting doping will be acceptor. Hence, the resultant semiconductor will behave as p-type.
Majority carrier concentration
Therefore,
Minority carrier concentration

The given information states that the intrinsic carrier concentration (n) of a Germanium (Ge) sample at room temperature is 1.5.
The intrinsic carrier concentration is a material property that represents the number of mobile charge carriers (either electrons or holes) at thermal equilibrium. In an intrinsic semiconductor, the concentration of electrons is equal to the concentration of holes, and this equilibrium concentration is known as the intrinsic carrier concentration.
Therefore, in the given Ge sample at room temperature, the concentration of both electrons and holes is 1.5.
