A single card is drawn at random from a standard 52 card deck. Work out in its simplest form:
P(10)
=

P(not 10)
=

There are four 10 cards in the deck, so P(10) = 4/52 = 1/13

P(not 10) = 1 - P(10). This is because the maximum probability is 1, and the card you draw will either be 10, or not a 10.

P(not 10) = 1 - 1/13 = 13/13 - 1/13 = 12/13

From all the steps above student B has steps in the correct order and

student A doesn't have steps in the correct order

Step-by-step explanation:

* Lets revise the steps of construct a parallel line to a given line from

 a given point

- The given is:

  line AB and point C doesn't lie on line AB

1. Draw a line that intersects points B and C

2. Place the compass on point B and swing an arc  that crosses line AB

   at point D and line BC at point E

3. Keep the compass at the same width, and place  it on point C , swing

   an arc that crosses line BC at point F

4. Open the compass to the width between points  D and E.

5. Keeping the compass at the same width, place it  on point F, and

    swing an arc that intersects the arc created from  line BC at

    point C, the two arcs intersected at point G

6. Draw a line through point C and point G. line CG parallel to line AB

* From all the steps above student B has steps in the correct order

  and student A doesn't have steps in the correct order
