A number cube will be rolled 100 times as part of an experiment. Which calculation would you use to predict the
number of times a 4 will be rolled?

sorry, i don't know i just need points, i'm new here. chao

< 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
