Answer:
240/2500
Step-by-step explanation:
A:event of drawing a blue marble from bag
P(A)=number of blue marble/total marbles
= 12/50
B:event of getting tails on tossing a coin
P(B)=total tails/total tosses
= 20/50
A∩B:event of getting a blue marble and tails on coin
As we know the two events are independent
Hence, P(A∩B)=P(A)×P(B)
=

Given:
The two numbers are
To find:
The highest common factor (HCF) of A and B
Solution:
We have,
...(i)
All the factors of A are prime but the factors of B are not prime. So, it can be written as
...(ii)
From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,
Therefore, the highest common factor (HCF) of A and B is 3.
