A standard deck of 52 playing cards contains 13 cards in each of four suits: hearts, diamonds, clubs, and spades. Four cards are drawn from the deck at random. What is the approximate probability that exactly three of the cards are diamonds?

answe

its a

step-by-step explanation:

true

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain

answer: 2/13 chance i think ( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)

the equation solved by kelsey is

⇒7 x-   →[given equation]

⇒ 7 x -1/2×(8 x)-1/2×(2)=6 →[distributive property]

⇒ 7 x- 4 x-1=6

⇒7 x- 4 x=6+1→ [ combining like terms]

⇒3 x=7 → [ subtraction and addition property of equality]

⇒x=7/3   →[ division property of equality]

so, we have used for properties to solve the equation

1. distributive property. 2. combine like terms. 3. subtraction and addition property of equality. 4. division property of equality.
