If the probability that will rain today is 5/8 what us the probability that it will not​

3/8

Step-by-step explanation:

1 - 5/8 = 3/8

1-5/8

3/8

the probability that it will not rain ☔ is 3\8

< 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
