Determine the likelihood of the following event: 
Drawing a red card from a standard deck of cards

• 1/2
• 13/52
• 1/4

What is probability?

• A number between zero and one
• The chance or the likelihood of an event happening
• The favorable outcomes divided by all the possible outcomes.
• All of the choices are true.
