Answer the following questions please

Solution

WE have 6 single, 4 dating and 2 engaged women.

P ( Single being called first) = 6 / 12

b)

This part of the question is sampling without replacement

P(Engaged friend) = 2/12

NOw there are 11 friends left and we need to call 1 single friend out of 6

P(single ) =6/11

So, combied probability = (2/12) * (6/11)

= 12 / 132 or 1/11 whichever answer is accepted over there.

Note: We multiply directly as the events are independent.

Hope this helps. Ask if you have any doubts.
