Answer:
(C)1 out of 5,005
Step-by-step explanation:
There are a total of 15 student friends.
Monica wants to invite 6 of her friends.
The number of ways this can be done is:
Therefore, the probability that friends Tessa, Guido, Brendan, Faith, Charlotte and Rhianna are chosen
You can remove the first plus sign to give:
-1.3 -4.9 [ because + x - = - ]
and by the same rule you can remove the the second plus sign to give
-1.3 -4.9 - 2.6
That means option b is out because it is positive.
straight away we can see that option D. equals the result, so it is in the running, so now can we eliminate c and a?
we can eliminate a because the minus ign outside the bracket multiplied by -4.9 inside the bracket produces + 4.9, which is not the answer, so that only leaves c.
once again, a plus sign outside the bracket does not produce -4.9 when muliplied by 4.9 inside the bracket inside option c, so we can eliminate option c.
