Answer Posted / raveender reddy
pick up one of the container from 2 container so the
probability is 1/2 and
means we are picking either container A or container B
from container A getting a blue ball the probability is 4/10
and
from container B getting a blue ball the probability is 40/100
so we are picking a blue ball either from container A OR
container B.
so the probability is=1/2{4/10+40/1000]
the answer is=2/5
