Is it possible to calculate the probability of intersection sets in this setting?

I have 44000 different cell clones in sample O, I donīt know how many copies of each.

I have 6 samples taken out of sample O (A-F).

Sample A containes 6900 different clones, B 2700, C 7000, D 4800, E 6100, F 7100

P(AnB)-> 0.009
P(AnC)-> 0.025
p(BnC)-> 0.009
P(AnBnC)->2.025E-6 is this the propability of one cell clone to be found in sample A,B and C?

Thanks for your help :-)
