Answer: The required probability is 0.26.
Step-by-step explanation: Given that there are 60 red marbles and 40 blue marbles in a box 10 marbles are picked without replacement.
We are to find the probability of selecting 6 red marbles.
Since the marbles are picked up without replacement, so it is a situation of combination.
Let S denote the sample space of the experiment of drawing 10 marbles and E denote the event that 6 marbles are red.
So,

Therefore, the probability of event E is given by

Thus, the required probability is 0.26.
The rule for clockwise rotation of 90 degrees about the origin is (-y, x).
So (-1,9) would now be (-9,1).
