According to the tree diagram below, what is the probability that someone buys a book that is hardcover and nonfiction
Rasek [7]

Whenever you have a decision tree like this, the probability of reaching a specific leaf is the multiplication of the probabilities of each step you have to reach the leaf.

So, in order to reach the "hardcover and nonfiction" leaf, we have to take the "buys hardcover" branch (probability 0.35), and then the "buys nonfiction" branch (probability 0.55).

Given what we said above, the probability for "hardcover and nonfiction" is

0.35\cdot 0.55=0.1925

Manny has $650 in his savings
Bumek [7]

Answer:

Interest Manny earns after 2 years is  $52

Step-by-step explanation:

Amount deposited = $650

Simple annual interest rate = 4%

To find: Interest after 2 years

We know that the formula to calculate the interest amount is

Simple interest (S.I.) =  \frac{Prt}{100}

where,

P is the initial amount deposited

r is the rate of simple interest in percentage

t is the time in years for which interest is to be calculated

Substituting the known values in the formula, we get

S.I =  \frac{650 x 4 x 2}{100}

   = 52

Hence the interest Manny earns after 2 years is  $52
