GUYS I REALLY NEED HELP!! THE STRUGGLE!!

Mazyrski [523]

Answer:

Last option is the correct answer.

Step-by-step explanation:

Total number of movies = 9+7+4=20

The total number of combinations of choosing 3 movies from total 20 is represented by 20C3. Then there are 9 action movies and we're choosing 3, the number of combinations will be 9C3,

Now, the probability of choosing all action movies will be:

$\frac{9C3}{20C3}$

As we know that probability of something which is not happening is given as : 1 - probability of something happening, so the probability of not choosing all action movies is given by: $1-\frac{9C3}{20C3}$

Hence, option D or last option is the right one.

I need helppp asap 7x+3=4x-9

Vesnalui [34]

Answer: -4

Step-by-step explanation: Hello! :) To get started we need to use the equation 7x+3=4x-9, First, we need to subtract 4x from both sides to get 3x+3=-9, then we need to subtract 3 on both sides to get 3x=-12, Finally, we need to divide both sides by 3 to get x = -4. So x = -4.

Hope this helps!
