If you have blue, green ,yellow and red what is the probability of spinning red twice

it they were asking probabilty of spinning red one time, like you know we would say 1/4.

but that want twice from us. so im multiplaying by itself.

(1/4)^2 = 1/16

good luck(:

< 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
