The pooled samples by combining the sample proportion to that of the successes in the each samples and combining the sample sizes.
P^ = (122+160)/(210+228)= 282/438
Then multiply this pooled sample with the two sample sizes:
Expected males = n1*^p = 210(282/438) = 135.21
expected females =n2*^p = 228(282/438) = 146.79
Thus the expected numbers of males are 135 and expected numbers of females are 147.
