Abag contains 25 marbles of the same size that are yellow, green, and purple. the probability of picking a yellow marble is 20%. the probability of picking a green marble is 50%. determine the probability of picking a purple marble from the bag and then classify the probability of picking a purple marble as likely or not likely to occur.

20% + 50% = 70%

100% - 70% = 30%

The probability of picking a purple marble from the bag is 30% which is not likely.

Step-by-step explanation:

< 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
