Let A be the event that house sales will decreases in the next 6 months and

B be the event that interest on housing loans will increase in the next 6 months


"P(A) = 0.6\n\\\\\nP(B) = 0.20\\\\\n\\\\\nP(A\\cap B) = 0.15"


The probability that interest rates increase and house sales decrease is:

"P(A\\cap B)" is 0.15


Hence option (a) is correct.
