Question 1191553
<br>
The question is open to different interpretations....<br>
The way I read it, the 2 red pens are indistinguishable, as are the 4 black pens.<br>
With that interpretation, there are 3 outcomes in the sample space, because the number of red pens among the 3 chosen can be either 0, 1, or 2.<br>
ANSWER: 3 possible outcomes
black, black, black
red, black, black
red, red, black<br>
