Suppose you just purchased a digital music player and have put 15 tracks on it. After listening to them you decide that you like

blsea [12.9K]

Answer:

Total songs = 15

Liked songs = 3

Un liked songs = 15-3=12

Find the probability that among the first two songs played

(a) You like both of them.

Probability that among the first two songs played you like both of them = $\frac{3}{15} \times \frac{2}{14} = 0.029$

(b) You like neither of them.

Probability that among the first two songs played you like neither of them = $\frac{12}{15} \times \frac{11}{14} = 0.629$

(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = $\frac{3}{15} \times \frac{12}{14}+ \frac{12}{15} \times \frac{3}{14}= 0.343$

(d) Redo (a)-(c) if a song can be replayed before all

(a) You like both of them. Would this be unusual?

Probability that among the first two songs played you like both of them = $\frac{3}{15} \times \frac{3}{15} = 0.04$

(b) You like neither of them.

Probability that among the first two songs played you like neither of them = $\frac{12}{15} \times \frac{12}{15} = 0.64$

(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = $\frac{3}{15} \times \frac{12}{15}+ \frac{12}{15} \times \frac{3}{15}= 0.32$

Joe is taking out a five year loan with a 7% interest rate compounded quarterly to buy a $4000 car. What will he have paid in to

Sergio [31]

Answer:

$5659.11

Step-by-step explanation:

We are given;

Time of loan maturity is 5 years
Rate of compound interest is 7% compounded quarterly
Principal amount of the car is $4000

We are required to determine the total amount he paid at the end of 5 years..

The concept being tested is compound interest;

We are going to use the compound interest formula;

Amount = P(1+r/100)^n

Where P is the the principal amount

r is the rate of interest

n is the interest periods

In this case;

n = (5 × 4) = 20

r = 7 ÷ 4 = 1.75 ( as the money was compounded quarterly)

Thus;

Amount =$ 4000 ( 1 + 1.75)^20

= $4000 (1.0175)^20

= $5659.11

Therefore, the money that Joe will have paid at the end of 5 years is $5659.11
