Answer:

(cos π/4, sin π/4) or approx. (0.707, 0.707)

Step-by-step explanation:

The length of the blue ray is 1.  That's the same for any ray drawn inside the circle.

Then a = cos π/4 and b = sin π/4.

The cartesian coordinates of the point (a, b) are

(cos π/4, sin π/4) or approx. (0.707, 0.707)

To answer this problem, the utilization of the provided formula is of utmost importance.

The formula to be used would be for the combination with no repetition since it is what is asked and possibly happens when involving the products mentioned in the problem. The formula would be

      n!                                              where in
-------------                                                   n = number of things to choose from
(n - r)! r!                                                      r = number of things needed to form

the symbol ! is called a factorial function which replaces the sequence of multiplying a number in a descending order.

lets substitute and solve

      13!
--------------
(13 - 6)! 6!

      13!
-------------
   (7!) 6!

A cube labeled 1 to 6, is tossed 6 times
slava [35]

Answer:

1/6

Step-by-step explanation:

If we're assuming that this is a six-sided die, then we can find that the results can be 1,2,3,4,5,6. Only 1 of those 6 numbers are 5, so the probability of the cube landing on 5 would be 1/6.
