If you choose one person from the group, you have a 12/20 chance of them being a girl. Now, if the first person is a girl, we have one less girl and one less person to choose from. So, the new probability for the second person is 11/19.
Then, we multiply the chances
12/20 * 11/19
3/5 * 11/19
33/95
3.5 x 7.3
Take it to the nearest tenth.
Does that answer your question?
4xV-2=11
(4 multiplied by the variable V subtracted by 2 equals 11).
Hope this helps, bud! :P
