Seventy percent of adults ages 50 and older want to reach their 100th birthday. You randomly select nine adults ages 50 and older and ask them whether they want to reach their 100th birthday. The random variable represents the number of adults ages 50 and older who want to reach their 100th birthday.

< 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
