    (b) Divide the total number of applicants into 1.00 to determine 
pre-preference probabilities.
    (c) Multiply each applicant's pre-preference probability by the 
applicable preference from Sec. 1.1622 (b)(2) or (b)(3).
    (d) Divide each applicant's probability pursuant to paragraph (c) of 
this section by the sum of such probabilities to determine intermediate 
probabilities.
    (e) Add the intermediate probabilities of all applicants who 
received a preference pursuant to Sec. 1.1622 (b)(2) or (b)(3).
    (f)(1) If the sum pursuant to paragraph (e) of this section is .40 
or greater, proceed to paragraph (g) of this section.
    (2) If the sum pursuant to paragraph (e) of this section is less 
than .40, then multiply each such intermediate probability by the ratio 
of .40 to such sum. Divide .60 by the number of applicants who did not 
receive a preference pursuant to Sec. 1.1622 (b)(2) or (b)(3) to 
determine their new intermediate probabilities.
    (g) Multiply each applicant's probability pursuant to paragraph (f) 
of this section by the applicable preference ratio from 
Sec. 1.1622(b)(1).
    (h) Divide each applicant's probability pursuant to paragraph (g) of 
this section by the sum of such probabilities to determine the final 
selection percentage.
