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

To find:
An irrational number that is greater than 10.
Solution:
Irritation number: It cannot be expression in the form of , where,
are integers.
For example: .
We know that square of 10 is 100. So, square root of any prime number is an example of an irrational number that is greater than 10.
First prime number after 100 is 101.
Required irrational number
Therefore, is an irrational number that is greater than 10.
