What is the probability of flipping a coin and it landing on heads? A. 1/4
B. 1/3
C. 1/2
D. 1/5

C. 1/2

Step-by-step explanation:

1/2 means 50%. When you flip a coin, there's a 50/50 chance you land on heads because there's only two sides to a coin.

< 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
