P(prod_i p_i^{k_i}|n)=?



Apologies if this is a stupid question.

What is the probability that n has the form prod_i p_i^{k^i}m, p_i prime?

I get: P(p|n)=1/p, hence

P(p^k|n)=1/p^k, and generally,

P(prod_i p_i^{k_i}|n)=prod_i p_i^{-k_i},

hence the probability that n is of the form prod_i p_i^{k_i}m, m\in N, is,

P(n=prod_i p_i^{k_i}m)=prod_i p_i^{-k_i}

Is this correct?

Many thanks,
