Answer:
it would be a 6/16 chance
add all the cards in the deck so 5 plus 6 plus 2 plus 3 that makes 16 so from there you see it asks what's the chance of her pulling a yellow card so if there's 6 in the deck of 16 that means there's a 6/16 chance of pulling a yellow card it's the same with others if it was what's the chance of pulling a blue it would be 3/16 chance (if it asked then convert the anerw into a decimal )
