The probability of choosing one correct number is 44/3939.
The prob. of choosing 2 s 44/3939 * 43/3938.
And so on...
In product notation it looks like this:
.
If you're wondering why i'm subtracting it's because each time you choose a number the # of choices decreases.
Answer:
C
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
Q(- 5, 2 ) → Q'(2, - 5 )
R(0, 5 ) → R'(5, 0 )
S(- 1, 2 ) → S'(2, - 1 )
i would say the first one and second one
because the point is an o and an dot at the same time
