Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24

hence 24 is the correct answer....


u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....

as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.



I know this is pretty much confusing ....but still I tried my best....

if anything troubles u here feel free to ask me

What number is q in the problem -8-q-10q=-9q+6
uranmaximum [27]
For this question you can say:
-8 -11q = -9q +6 
so now you can add +9q on both sides and +8 on both sides of the equation:
-11q + 9q = 8 + 6 
-2q = 14 
q = 14/-2 
q = -7 :)))
I hope this is helpful

The probability that you roll a 3 on a six-sided die is . The probability that you flip a coin that lands on tails is . The prob
aivan3 [116]

Answer:

1/6; 1/2; 1/12; P(T|3) = 1/2; therefore, events are independent because P(T|3) = P(T).

Step-by-step explanation:

The probability of rolling a 3 on a six-sided die is 1/6.  This is because there is one 3 out of 6 possibilities.

The probability of flipping a coin on tails is 1/2.  This is because there is one side "tails" out of 2 possibilities.

The probability of rolling a 3 and flipping tails is 1/6(1/2) = 1/12.

P(T|3) = P(3 and Tails)/P(3) = 1/12 / (1/6) = 1/12(6/1) = 6/12 = 1/2

Since P(T|3) = P(3), these are independent events.

When adding √9 and -7, which type of number is the sum?
dezoksy [38]

We are given numbers √9 and -7.

Square root 9 is a perfect square.

Square root 9 = 3.

So, if we add square root 9 and -7, we would get

√9 + -7 = 3 -7 = -4.

So, we got a negative whole number.

<em>A negative or positive whole number is called an integer</em>.

So, it's an integer.

<h3>Therefore, correct option is D. Integer.</h3>

The answer is 2/5.

There is an 8/20 chance that the next person will receive a window seat. You simplify that probability to get your answer. 8/20 becomes 2/5. So the answer is 2/5.
