<h3>Part one :</h3>
As it is given :
Present age of mom : Present age of son = 6 : 1
Therefore let :
<h3>Part two :</h3>
Ages after 10 year :
<h3>Part three :</h3>
The ages after 10 years are given in rational of 8 : 3.
Which means :
Mom's age after 10 years : Son's age after 10 years = 8 :3.
Now :


So :

Answer: The required probability of event B is P(B) = 0.37.
Step-by-step explanation: For two events A and B, we are given the following probabilities :
P(A) = 0.34, P(A ∩ B) = 0.27 and P(A ∪ B) = 0.44.
We are to find the probability of event B, P(B) = ?
From the laws of probability, we have

Thus, the required probability of event B is P(B) = 0.37.
