Question

A collection of books consist of 6math books and 4 english books . Ali picks a book at random from the collection. find the probability he choose either a math or an english​

Answer 1

Answer:

Ali has a 33.3% chance of choosing a english book and a 67% chance of choosing a math book.

Step-by-step explanation:

So from this problem we know there are 6 math books and 4 english books. In total we have 10 books. Now think of this in the form of fractions:

6/10 are math books (simplify the fraction to 3/5)

4/10 are english books (simplify the fraction to 2/5)

There is a 4/10 chance she Ali will not pick an english book, so we divide the possibility of 6/10 that she will by that she will not:

$\frac{6}{10}$  ÷ $\frac{4}{10}$ = 0.333

Now multiply this number by 100 to get:

Ali has a 33.3% chance of choosing a math book.

Now using these same steps but reversed you can calculate the chances of her choosing a math book:

$\frac{4}{10}$  ÷ $\frac{6}{10}$  = 0.667

Now multiply this number by 100 to get:

Ali has a 66.7% chance of choosing a math book.
