A jar is filled with 74 different colored marbles, 10 of which are red, 38 of which are blue, and 26 of which are green. A playe
Alex_Xolod [135]

Solution :

Colored marble            Prize

     Red ----  10               20

    Blue --- 38                 10

   Green --- 26               5

P(red)  =  10/74  =  5/37

P(blue)  =  38/74  =  19/37

P( green)  = 26/74  =  13/37

Therefore,

 X      →     Red          Blue      Green

P(X)           5/37        19/37      13/37

The expected values are :

$20 \times \frac{5}{37} - 10 \times \frac{19}{37} - 5 \times \frac{13}{37}

= -4.189

Thus it is not profitable to play the game.

What is the largest three-digit number divisible by 24 and 54?
tensa zangetsu [6.8K]

Answer:

The largest three-digit number divisible by 24 and 54 is:

  • <u>864</u>

Step-by-step explanation:

To identify the largest number what I did was dividing 999 (the largest whole three-digit number of all) in the first number given (24):

  • \frac{999}{24}=41.625

With this number, you know that you must multiply 24 by a number like 41 or less until you find a number that can be divisible by 54 and obtain a whole number, so:

  • 24*41= 984/54= 18.22 (how the number obtained is not a whole number, this is not the correct).
  • 24*40= 960/54= 17.77 (this is not).
  • 24*39= 936/54= 17.33 (this is not).
  • 24*38= 912/54= 16.88 (this is not).
  • 24*37=888/54= 16.44 (this is not).
  • <u>24*36= 864/54= 16 (This is the correct</u>).

Now, you have identified that the number 864, you can prove it by dividing this in 24 and 54:

  • \frac{864}{24}=36
  • \frac{864}{54}= 16
