1. The game UNO uses cards which have two characteristics: each card has a colour (yellow, red, green or blue) and a number (from 0 to 9).

if a card is yellow or red, the score is the number on the card plus 2 if a card is blue, the score is the number on the card plus 1 if a card is green, the score is the number on the card.

The probability distribution for the score from playing this game once has the following values:
