Answer:
Step-by-step explanation:
Given : In a state where license plates contain six digits.
Probability of that a number is 9 =
[Since total digits = 10]
We assume that each digit of the license number is randomly selected .
Since each digit in the license plate is independent from the other and there is only two possible outcomes for given case (either 9 or not), so we can use Binomial.
Binomial probability formula: 
, where n= total trials , p = probability for each success.
Let x be the number of 9s in the license plate number.

Then, the probability that the license number of a randomly selected car has exactly two 9's will be :

Hence, the required probability = 0.098415

Answer:
The number of whole dumpling does Omar make is 14 .
Step-by-step explanation:
Given as :
The number of cups does Omar has to make dumplings = x = 2
i.e x = 
or, x = 
Again
The number of cups uses for each dumpling = y = 
i.e y = 
Let The number of whole dumpling does Omar make = z
So, number of whole dumpling does Omar make = 
Or, z = 
Or, z = 
Or, z = 
∴ z = 7 × 2
i.e z = 14
So, The number of whole dumpling does Omar make = z = 14
Hence, The number of whole dumpling does Omar make is 14 . Answer
The value of x is: 75°
360° - 128° - 85° - 72° = 75°
