Answer:

Step-by-step explanation:

From what I saw on google for what "one to one" means, It's basically meaning that the bottom of that quadratic function is at point (0 , 0) and hits both (-1 , 1) and (1 , 1) on the graph.

wo urns contain white balls and yellow balls. The first urn contains 3 white balls and 6 yellow balls and the second urn contain

vlada-n [284]

Answer:

Answer is

$\frac{7}{30}$

Step-by-step explanation:

Given that there are two urns. First urn contains 3 white balls and 6 yellow balls and the second urn contains 7 white balls and 3 yellow balls.

A ball is drawn from each urn.

Probability for ball from urn I is white = no of white balls/total balls in I urn

$= \frac{3}{9} =\frac{1}{3}$

Probability for ball from urn II is white = no of white balls/total balls in I urn

$=\frac{7}{10}$

Since drawing one ball from each urn is independent of the other we find

Prob that both balls are white=

Prob that ball from I urn is white *Prob that ball from II urn is white

= $= \frac{7}{10} *\frac{1}{3}\\=\frac{7}{30}$
