Two urns contain white balls and yellow balls. the first urn contains 5 white balls and 8 yellow balls and the second urn contains 9 white balls and 2 yellow balls. a ball is drawn at random from each urn. what is the probability that both balls are white?

1st urn : 5 white, 8 yellowtotal of 13 balls
P(white) = 5/13

2nd urn : 9 white, 2 yellow...total of 11 balls
P(white) = 9/11

P(both events happening) = 5/13 * 9/11 = 45/143 <=

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
