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

3y+z=am-4y look for y
LenKa [72]

The value of y is am-z/7

<h3>How to calculate the value of y ?</h3>

The expression is given as follows

3y +z= am-4y

The first step is to collect the like terms in both sides, this way the numbers that both have y as their coefficient will be on the same side

3y + 4y= am-z

y(3+4)= am -z

7y= am-z

Divide both sides by the coefficient of y which is 7

7y/7= am-z/7

y= am-z/7

Hence the value of y in the expression is am-z/7
