how can we calculate P(a|b,c) ?

what is the emaning of a,b and how can we simply this equation like p(a|b)

]]>P(a|b,c) = (P(b,c|a)*P(a))/P(c)

P(b,c|a) is probability b and c given a

If so, Can we write P(b,c|a)

P(b,c|a)=P(b|a) * P(c|a) is it correct?

unlike P(a|b,c) =P(a|b intersect c) =P(a intersect b intersect c) /P(a intersect b)

which one is correct. Can you help me for above equation…
