Step-by-step explanation:
All the possible outcomes are listed below if the condition of at least 2 books from each subject has to be satisfied
Option 1 - 3 books from mathematics, 2 books from chemistry and 2 books from astrology
Option 2 - 2 books from mathematics, 3 books from chemistry and 2 books from astrology
Option 3 - 2 books from mathematics, 2 books from chemistry and 3 books from astrology
The probability for option 1 = 3/10 x 2/8 x 2/5
= 0.03
The probability for option 2 = 2/10 x 3/8 x 2/5
= 0.03
The probability for option 3 = 2/10 x 2/8 x 3/5
= 0.03
The final probability = Probability of option 1 + Probability of option 2 + Probability of option 3
= 0.09

y ≈ 6.7 ( to 1 dec. place )
You need to take the estimate and add the VAT. Then take this total cost and divide it by 12 to solve for the monthly payment needed...
(1450)(105/100)/12=126.875
Clearly, a monthly payment of 130 is enough to cover the yearly cost.
