It is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.
As given in the question,
Number of cards are unknown.
Number of red cards are unknown in the starting of experiment.
Number of times process done =10
For binomial random variable number of red cards should be known.
Therefore, it is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.

Answer:
60
Step-by-step explanation:
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 172 = 120% × Y
STEP 272 =
120
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 120 we will arrive at:
STEP 3Y = 72 ×
100
120
STEP 4Y = 72 × 100 ÷ 120
STEP 5Y = 60
Finally, we have found the value of Y which is 60 and that is our answer.
You can easily calculate 72 is 120 percent of what number by using any regular calculator, simply enter 72 × 100 ÷ 120 and you will get your answer which is 60

Answer:
Option B is true
Step-by-step explanation:
The formula for Cos is Adjacent/hypotenuse. 12 is Adjacent to angle e, and 17 is the hypotenuse.
The pattern is dividing by 4 so it would be: 640 (divided by 4), 160 (divided by 4), 40 (divided by 4), 10 (divided by four), 5/2.
The next number would be 10/4 or 5/2 when simplified. (I’d go with 5/2 because teachers liked simplified numbers)
