Two urns contain white balls and yellow balls. The first urn contains 2 white balls and 7 yellow balls and the second urn contai
2 answers:
Answer with Step-by-step explanation:
A: white ball is drawn from first urn
P(A)=number of white balls in first urn/total balls in first urn
= 2/9
B: white ball is drawn from second urn
P(B)=number of white balls in second urn/total balls in second urn
= 10/14
A∩B: white ball is drawn from both urns
Since, events A and B are independent
Hence, P(A∩B)=P(A)×P(B)
=
= 10/63
Hence, probability that both balls are white is:
10/63

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the image, the line goes through the following points:
So, the slope is:
Thus, the equation is of the form:
We substitute a point and find "b":
Finally, the equation is:
