Question

A set of cards includes 20 yellow cards, and 24 blue cards. What is the probability, written in decimal form, that a blue card is chosen at random? (Help please)

Answer 1

.54 I believe. 
20 yellow and 24 blue = 44 cards in all
divide 24 by 44 and you get a .54 repeating decimal. 

Answer 2

0.55 
Number of favorable outcome/Total number of possible outcome
24/(20+24)
