Solution


Here we have an organization of 700 members. Now there are 120 lawyers in the 700 members thus there is 580 not lawyers. Now we have to choose 2 not lawyers.

So the probability becomes \(\frac{580}{700}*\frac{579}{699}\).

Now we can use the calculator available at the GRE to find the value and it is close to 0.7.

Note that the second term is \(\frac{(580-1)}{(700-1)}\) since one not lawyer was already selected in the first attempt.
