Pls answer this in full sentences :)

30

Step-by-step explanation:

There are two even numbered balls (2, 4) which makes the probability 2/5. If you are planning to repeat the process 75 times, your equation would look like .

< 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
