What is the probability of drawing the compliment of a king or a

inna [77]

Answer:

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards = 0.846

Step-by-step explanation:

Step(i):-

Let 'S' be the sample space associated with the drawing of a card

n (S) = 52C₁ = 52

Let E₁ be the event of the card drawn being a king

$n( E_{1} ) = 4 _{C_{1} } = 4$

Let E₂ be the event of the card drawn being a queen

$n( E_{2} ) = 4 _{C_{1} } = 4$

But E₁ and E₂ are mutually exclusive events

since E₁ U E₂ is the event of drawing a king or a queen

step(ii):-

The probability of drawing of a king or a queen from a standard deck of playing cards

P( E₁ U E₂ ) = P(E₁) +P(E₂)

$= \frac{4}{52} + \frac{4}{52}$

P( E₁ U E₂ ) = $\frac{8}{52}$

step(iii):-

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards

$P(E_{1}UE_{2}) ^{-} = 1- P(E_{1} U E_{2} )$

$P(E_{1}UE_{2}) ^{-} = 1- \frac{8}{52}$

$P(E_{1}UE_{2}) ^{-} = \frac{52-8}{52} = \frac{44}{52} = 0.846$

Conclusion:-

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards = 0.846

This is the total of everything you can draw.

in this case it would by 55.

We set this as the denominator and set the numerator to the ammount of times orange has been drawn.

This would result in our answer.

FREE BRANLIEST TO CORRECT ANSWER WITH EXPLANATION!!!!!!!!!!! RNN

Tomtit [17]

Answer:

The correct answer is choice C.

Step-by-step explanation:

If you were to input the weight in ounces of each data set into all of the answers, you'll find that only option C meets the requirement. If the weight in ounces is 12, 12 * 600 = 7,200, which is the same as the cost in dollars of that set. If the weight in ounces is 22, 22 * 600 = 13,200, which is the same as the cost in dollars of that set. If the weight in ounces is 32, 32 * 600 = 19,200, which does equal the same as the cost in dollars of that set. So the correct answer is choice C.
