Option B

The probability of getting a king card is 1/13 or 0.077, so option B is correct.

<u>Solution:</u>

Given that , The first card selected from a standard 52-card deck was a king.  

It is returned to the deck

We have to find what is the probability that a king will be drawn on the second selection?

Now, the first selected card is king and it is returned to the deck.

So it has no effect on the second selection card.

Then, we have to find probability to get a king  

\text { probability }=\frac{\text { favourable outcomes for a king }}{\text { total possible outcomes }}=\frac{4 \text { king cards }}{52 \text { cards in total }}=\frac{4}{52}=\frac{1}{13}

Hence, the probability of getting a king card is 1/13 or 0.077

NikAS [45]

Answer:

0.33

Step-by-step explanation:

Let A denote an event. The odds of the horse finishing second is 33 to 67.

From the information, the total outcomes of event A is:

Total \ Outcomes, A=Favorable +Unfavorable\\\\=33+67\\\\=100

Hence, there are 100 total outcomes. The probability of the horse finishing second is calculated as:

p=\frac{n(A_f)}{n(A_u)}\\\\\\=p=\frac{33}{100}\\\\=0.33

Hence, the probability of finishing second is 0.33

olya-2409 [2.1K]
Y=3(x+1)(x-5)
I'm going to ignore 3 for now, but will add it later.
FOIL the (x+1)(x-5)
F = multiply the First numbers      x and x
O = multiply the Outside numbers      x and -5
I = multiply the Inside number        1 and x
L = multiply the Last numbers        1 and -5
3(x^2 + -5x + 1x + -5)
add -5x and x
3(x^2 + -4x + -5)
multiply the numbers inside the parenthesis by 3
3x^2 + -12x + -15
