Answer:
2/9
Step-by-step explanation:
The probability of getting any letter once is 1/3
The probability of getting any combinations = 1/3 * 1/3 = 1/9
The probability of getting two of the combinations = 1/9 + 1/9 = 2/9
By adding 20+20+19+13+x and dividing by 5 you will receive the answer. Therefore by substituting numbers, 8 will give you the correct average.
20+20+19+13+8 = 80
80/5 = 16.
Therefore x = 8
If I have helped you out, help me out by making me the brainliest answer.
You would do 16 + 40 = (8 X 2) + (8 X 5) = 8(2 + 5)
Hope this helps best of luck :)
