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

6/9 because when u take it away, you have 9 total cards and 6 kings

and there is 1 king card
so the probability would be...(@amber_heart_ try to answer)
@amber_heart_ What do you think it is?
@jim_thompson5910 @heretohelpalways @Plasmataco
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
oh, never mind,I read the question wrong, sorry
but i am right about 1/7 right?
oh ok lol
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
