Say there are 100 people in that group, then there would be 0.6*0.45*100=27 women lawyers, which means that the probability that the member selected is a woman lawyer is favorable/total=27/100.

Answer: C.

This is a two-part probability question. We should first notice that since our answer choices are in decimal form, we can use a real numerical value for the total number of members of the study group. A convenient number to use is 100.

We are first told that 60 percent of the members in the group are women. Thus we can say:

0.6 x 100 = 60 women

We are next told that 45 percent of these 60 women are lawyers. We can then say:

0.45 x 60 = 27 women lawyers

Finally, we need to determine the probability of selecting a woman lawyer from the group. Since there are 100 total members and 27 of them are women lawyers, the probability is 27/100 = 0.27.

Answer C.

0.6*0.45 =(6/10) * (45/100) = 27/100 =0.27

Because we're working with percentages, using 100 people as the total makes things easier. Also,

Total Number of People: 100

60% of those people are women: 100 * \(\frac{6}{10}\) (Converting and reducing those percentages into fractions makes it easier to calculate quickly)

45% of those women are lawyers: 100 * \(\frac{6}{10}\) * \(\frac{45}{100}\)

100 * \(\frac{3}{5}\) * \(\frac{3}{20}\) = 27 people who are women and lawyers

27/100 = 27%
