Ming has a standard 52-card deck. A standard 52-card deck has 4 suits (♠, ♣,♦, and ♥) and an equal number of cards of each suit.

soldier1979 [14.2K]

Answer:

Option D.

Step-by-step explanation:

Total number of cards = 52

Total number of cards of each suit (♠, ♣,♦, and ♥) = 13

The probability of getting a card of heart is

$\text{Probability of getting a card of heart}=\frac{\text{Number of heart cards}}{\text{Total number of cards}}$

$\text{Probability of getting a card of heart}=\frac{13}{52}$

$\text{Probability of getting a card of heart}=\frac{1}{4}$

The probability of getting a card other then heart is

$1-\frac{1}{4}=\frac{3}{4}$

If Ming randomly draw a card from the deck 300 times, putting the card back in the deck after each draw, then the number of cards she will draw something other than a heart is

$300\times \frac{3}{4}=225$

Close to 225 times but probably not exactly 225 times.

Therefore, the correct option is D.

Solve for x. 3(3x + 3) - 5x – 4= 25

Alexeev081 [22]

Answer:

x = 5

Step-by-step explanation:

$3(3x + 3) - 5x - 4= 25\\\\9x+9-5x-4=25\\\\9x-5x+9-4=25\\\\4x+5=25\\\\4x+5-5=25-5\\\\4x=20\\\\\frac{4x=20}{4}\\\\\boxed{x=5}$

Hope this helps.
