The measurement of heavy quark cross-sections provides important tests of the QCD theory. This paper reviews recent measurements of single b-quark and correlated b-quark cross-sections at CDF. Two new measurements of the single b-quark production at CDF agree with the first result from CDF Run II. This clarifies the experimental situation and confirms the recent agreement of theoretical prediction with data. A new measurement of the correlated bb cross-section with dimuon events at CDF is presented. It agrees with theory and it does not bb confirm the anomalously large bb cross-section seen in Run I by CDF and DØ in dimuon events.
