SOlution:-
The probability of selecting 4 science books and 3 maths books is 0.2961.
Total number of books = 23
Number of ways of selecting 7 books = 23C7 = 245157
Number of ways of selecting 4 science books and 3 maths books = 11C4 × 12C3 = 330 × 220 = 72,600
The probability of selecting 4 science books and 3 maths books = 72600/245157 = 0.2961
