Question 199852
If 40%  of  total  are men ,,,,then,, 60%  are  women
.
if 30 % of men  attend,  then  .3 * .4 = .12  of  total attend
.
If 20 % of  women  attend,  then .2 * .6 = .12 of  total  attend
.
Total  attendance  is  .12 +.12 = .24  or  24%  of  total
.
check
.
Let  100  =  plant  Total
40 % are  men ,,,,.4 * 100  =40,,of  them 30% attend,,40 * .3 =12  men  attend
60 %  are  women = .6 *100 = 60,,,of  them 20% attend,, 60 * .20 = 12  women
Total  attendance  is  12 +12 = 24,,,,or  24 / 100 = 24 %,,,,,ok
