Assume that the box contains 11 balls: 4 red, 4 blue, and 3 yellow. as in the text, you draw one ball, note its color, and if it is yellow replace it. if it is not yellow you do not replace it. you then draw a second ball and note its color.
(1) what is the probability that the second ball drawn is yellow?

(2) what is the probability that the second ball drawn is red?

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

< 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
