p(1 science and 2 mathematics books)

Step-by-step explanation:

Given: The number of Mathematics books = 4

The number of English books =3

The number of science books = 6

Total number of books :

If Laura opens the bag and selects books at random, then the probability to pick one science book is given by :_

Hence, the probability to pick one science book is .

b
