e=9
sorry thats all i know:(
Step-by-step explanation:
4 to 7......add them = 11
4/11 * 33 = 132/11 = 12
7/11 * 33 = 231/11 = 21
Answer:
Answer is

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

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

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
=
To subtract fractions, let's put a generic example.
Be the fractions
(a / b) - (c / d)
With a, b, c and d other than zero.
The subtraction of fractions is given by:
(a / b) - (c / d) = ((a * d) - (c * b)) / (b * d).
If the fractions have the same denominator then the subtraction is
(a / b) - (c / b) = (a-c) / (b)
answer
(a / b) - (c / d) = ((a * d) - (c * b)) / (b * d)
(a / b) - (c / b) = (a-c) / (b)
