..

Answer 5

the prob of drawing a white ball from the first urn is number of white balls over the total number of balls (2/9) ; the prob of drawing a white ball from the 2nd urn is the number of white balls in it over the total number of balls.(3/13). Since these are independent events (the drawing from one urn has no effect on the drawing from the 2nd urn), you would multiply the two probabilities together.

Answer 6

2/9 x 3/13

Answer 7
