Question

Tessa keeps seven cards with the picture of a king and three cards with the picture of a queen on a table face down, so the pictures are hidden. She mixes up the cards then turns over one card and finds the picture of a king on it. She removes this card from the table and turns over another card.

What is the probability that the card Tessa turns over has a picture of a king on it?

fraction 1 / 7
fraction 2 / 9
fraction 6/ 10
fraction 6 / 9

Answer 7

@amber_heart_ What do you think it is?

Answer 9

@jim_thompson5910 @heretohelpalways @Plasmataco

Answer 10

yup

Answer 11

plasmataco had the right idea

after throwing the king away on the first draw
7 -1 = 6 kings left
10-1 = 9 cards total

probability of king on second draw = (# of kings left)/(# of cards total left)
probability of king on second draw = 6/9 = 2/3

Answer 12

oh, never mind,I read the question wrong, sorry

Answer 13

but i am right about 1/7 right?

Answer 14

oh ok lol

Answer 15

No. There are 7 kings. 10 cards in total. When u take away a king, you have 6 kings and 9 cards. The odds of drawing another king is 6/9
