A man has n keys on a key ring, one of which opens the door to his apartment. Having celebrated a bit too much one evening, he r

schepotkina [342]

Answer:

The value is $P(3) = \frac{1}{n}$

Step-by-step explanation:

From the question we are told that

The number of keys is n

The number of keys remaining after the first key is chosen is n-1

The probability that he gains entrance with the first key he selects is $\frac{1}{n}$

Generally the probability that the first key does not open the door is

$p(F_1) = 1 - \frac{1}{n} = \frac{n-1}{n}$

Generally the number of keys remaining after the second key is chosen is

n-2

Generally the probability that he gains entrance with the second key he selects is

$\frac{1}{n-1}$

Generally the probability that the second key does not opens the door is

$P(F_2) = 1- \frac{1}{n-1} = \frac{n-2}{n-1}$

Generally the probability that he gains entrance with the third key he selects is

$\frac{1}{n-2}$

Generally the probability that the door opens with the third key

$P(3) = p(F_1) * P(F_2) * \frac{1}{n-2}$

=> $P(3) = \frac{n-1}{n} * \frac{n-2}{n-1} * \frac{n-2}{n-1}$

=> $P(3) = \frac{1}{n}$

Note :

All the outcome of the events are independent

WHEN adding integers and the signs are different, how do you know what the sign will be?

Neko [114]

Step-by-step explanation:

when you add integers remember that the positive integers move you to the right (so the integer will increase) and negative integers move you to the left (so the integer will decrease)

Hope this helps.

If x+4/4 = y+7/7 then x/4=___

muminat

Please, enclose those binomials x+4 and y+7 inside parentheses:

(x+4) / 4 = (y+7) / 7. Find (x/4).

Let's solve the above equation for x:

x+4 = 4(y+7)/7. Then x = 4(y+7) / 7 - 4

Last, divide all 3 terms by 4: x/4 = (y+7) / 7 - 1 (answer)

y + 7 - 7
You could also type this as x/4 = ------------- = y/7
