so there are twenty cards right, 2 cards are yellow birds, and 4 cards have the number 5 on them (5 is the only number greater than 4 on these cards, selecting one single card at random could yield any of the 20 cards. the chance to select a yellow bird or a number greater than 4, is the sum of favorable outcomes divided by the total number of outcomes

OpenStudy (unklerhaukus):

add up the favorable outcomes i.e. 2 two birds + 4 numbers greater four and divide by the total number of possible outcomes i.e 20 6/20
