We present a measurement of the correlated bb-bar production
cross section. The data used in this analysis were taken with the
upgraded CDF detector (CDF II) at the Fermilab Tevatron collider, and
correspond to an integrated luminosity of 742 pb-1. We utilize muon
pairs with invariant mass 5 < m_mu mu < 80 GeV/c2 produced by b
and b-bar quarks with p(t) > 2 GeV/c and |y| < 1.3, we measure
sigma_b --> mu, b-bar --> mu = 1549 +/- 133 pb. We compare
this result with theoretical predictions and previous measurements.
We also report the measurement of sigma_c --> mu, c-bar --> mu,
by-product of the study of the background to bb-bar production.
