a standard deck of 52 playing cards contains four of each numbered card 2–10 and four each of aces, kings, queens, and jacks. two cards are chosen from the deck at random. which expression represents the probability of drawing a king and a queen?

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
