-2 with a exponent six
DIA [1.3K]
-2^{6} &#10;&#10; =  -2 with a exponent six
Well Exponents mean that you multiply the number 6 times. 
Soo..
-2^{6} = -2 x -2 x -2 x -2 x -2 x -2 = 64 

So <span>-2^{6} = 64

Good Luck! :)

We are to find the Probability the someone buys a book that is paperback and fiction.

Let P(F) represents the event that the book is fiction and P(P) represents the event that the book is paperback. We are to find P(F∩P)

P(F∩P) = P(F) x P(P)

From the tree diagram we can see that:

P(F) = 0.45
P(P) = 0.65

Using the values, we get:

P(F∩P) = 0.45 x 0.65 = 0.2925

So, the Probability the someone buys a book that is paperback and fiction is 0.2925.

So, option B gives the correct answer
