There are 5 cards with a picture of a rose and 3 cards with a picture of a daisy. alia keeps all the cards down on a table with the pictures hidden and mixes them up. she then turns over one card and finds the picture of a rose on it. she removes this card from the table and turns over another card without looking. what is the probability that the card that alia turns over has a rose on it? 4 over 7 5 over 8 5 over 7 4 over 5

The answer would be 4 over 7

this is because there were 8 cards in total to begin with but she removes one leaving only 7; that would result in the bottom number because it is the total

then the top number would be the amount of rose cards left so in this case 4

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
