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
=
Answer:
Step-by-step explanation:
a. 3-4x=-7-4x
3=-7. no solution
b. 15 - 2x = -7x
15 = -5x
x=-3. one solution
c. 7y-21=6y-21
y=0
1. -3x+4=-3x+7
4=7
2. 10+2x = 5x+2
8=3x
x=3/8
3. x+5=x+5
Answer:
Therefore the probability that the card is not brown is
.
Step-by-step explanation:
Probability: Probability is the ratio of the favorable outcome to the total outcome.

Given that, a box contains 2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.
Total number of cards= (2+4+6)=12
∴P(getting a brown card)



∴P(not getting a brown card)
=1 - P(getting a brown card)


Therefore the probability that the card is not brown is
.
