You take 120/3=40
So you have 40
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 :

= -4.189
Thus it is not profitable to play the game.

Answer:
The largest three-digit number divisible by 24 and 54 is:
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):
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:
Answer:
4 friends, 40$, so each had 10$
40/4=10-7.5= 2.5
Each had $2.50 left
