According to the Venn diagram below, what is P(An Bric)

From the Venn diagram the value of:
P(A∩B∩C)=3/25
We are asked to find the probability of A∩B∩C.
We know that the probability of A∩B∩C is calculated as the ratio of the values of the region to the total value (i.e. whole of the given universal set)
The value of region A∩B∩C is 6.
and the value of total region is: 50
( since: 9+5+8+4+6+2+7+9=50)
Hence,
P(A∩B∩C)=6/50
On writing it in the simplest fraction we get:
P(A∩B∩C)=3/25
