If you have 6 cars, but there is only room in your driveway for 3 cars, in how many ways can you arrange the cars in your drivew

Svetradugi [14.3K]

If the order does not matter, cars can be arranged in 20 ways

If an order is important, cars can be arranged in 120 ways

The probability that the three newest cars end up parked in the driveway is 0.167

1. If the order does not matter, combination is used

$\left ({n} \atop {r}} \right.)=\frac{n!}{r!(n-r)!}$

Here, n=6 r=3

using formula,we get

$\left ( {{6} \atop {3}} \right)=\frac{6!}{3!3!} =5*4=20$

2. If an order is important, Permutation will be applicable

$^{n}P_{r} = \frac{n!}{(n-r)!} \\$

∴ $^{6} P_{3} =\frac{6!}{3!(6-3)!}=\frac{6!}{3!} =120$

3. the probability that the three newest cars end up parked in the driveway

P= $\frac{No. of possible outcomes for 3 cars}{total possibilities}$

= $\frac{6*4*5}{6!}$

= $\frac{120}{720}$

= $\frac{1}{6}$ ≈ 0.167

Hence, If the order does not matter, cars can be arranged in 20 ways

If an order is important, cars can be arranged in 120 ways

The probability that the three newest cars end up parked in the driveway is 0.167

Does anyone understand?

Sholpan [36]

so, Buttons Etc. sells buttons at $50 + 1.10 for each button, and Logos sells buttons fro $40 + 1.10 for each button.

let's say that "b" is the amount of buttons Crusader Pep Club is going to buy.

let's take a look at a few buttons prices for Buttons Etc.

1 button.................. 50 + 1.10(1)

2 buttons............... 50 + 1.10(2)

3 buttons............... 50 + 1.10(2)

4 buttons............... 50 + 1.10(4)

5 buttons............... 50 + 1.10(5)

b buttons............... 50 + 1.10(b)

let's take a look at the prices at Logos

1 button.................. 40 + 1.10(1)

2 buttons............... 40 + 1.10(2)

3 buttons............... 40 + 1.10(2)

4 buttons............... 40 + 1.10(4)

5 buttons............... 40 + 1.10(5)

b buttons............... 40 + 1.10(b)

when both companies are the same price, the price equation for Buttons Etc equals the price equation for Logos, namely 50+1.10b = 40 + 1.10b.

when does that occur? At how many buttons?

50+1.10b = 40 + 1.10b

10 ≠ 0

from the system of equations, we end up with 10 = 0, which is not true of course 10 ≠ 0, which is another way to say there's no solution to the system, namely, the equations' graphs never touch each other.

if you recall the slope-intercept form, notice, both have the same slope, so the lines are parallel, and the y-intercept differs, so they never touch each other.

so, since there's no solution, the companies Buttons Etc and Logos sales of buttons will never yield the same price, the prices will always differ for the same amount of buttons sold.

WINSTONCH [101]

If the divisor is greater than the dividen then you know that the answer is going to be more than one. But if the divisor is smaller than the dividen then you know that the answer is going to be less than one like a decimal.
