No, its against the rules.
No. The person who put down the wild card or draw four must still pick a color, the next player must still draw four and the game must continue on as usual. Hope this helped!
no way are you crazy
You put down one card each turn, unless told to draw a card or are skipped.
Yes you can. There are many different ways of playing. Some people put a +4 card over a +2 card and some don't (I recommend to do it the +4 over +2 way)
Uno is just a commercial version of the traditional game "Crazy Eights". The numbers 0 to 9 mean just what they say. The Reverse means the game play is Reversed. That is if the game play is clockwise, playing a Reverse makes it counterclockwise and vice-versa. The Skip means that the next player is skipped, that is he loses his turn. The Draw Two means the next player must draw two cards and loses his turn. The (regular) Wild can be played at any time. The Wild Draw Four can only be played if the player is out of the current color. The next player must then draw four cards. When a player plays a (regular) Wild or Wild Draw Four, he must announce the new color. I hope this is clear.
tally
The chance of NOT drawing a face card both times in a row is 1/4 (a half times a half). That means that the chance of drawing at least one (possibly 2) face cards is 3/4.
They must draw 2 cards and miss a turn, however if they have another draw 2, they can put this ontop and make the next person draw 4!
You cannot add a draw 2 on top of a draw 4 card. Nothing beats the Draw 4, it automatically takes your turn away. You can put a Draw 4 on top of a Draw 2 but ONLY if you do not have any more of that color card in your hand. You can also risk putting a Draw 4 on top of a color that you do still hold in your hand, but another player can call your bluff (because by using it you are saying you do not have any of that top color in your hand) and you will either have to take the entire discard pile or draw 4 cards depending on how you want to play.
1 - the chance to draw 2 jacks - the chance to draw no jacks leaves you with the chance to draw just one by elimination. 1 - (1/3)*(1/3) - (2/3)*(2/3) 1 - 1/9 - 4/9 1 - 5/9 4/9
2x2=4 (four)
Use four to make a normal square and put two lines on top of another
