Three cards are randomly selected from a standard 52-card deck, one at a time, with each card re- placed in the deck before the

hammer [34]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Three cards are randomly selected from a standard 52-card deck.

Number of heart cards in a deck = 13

Each card replaced in the deck before the next one is picked.

Probability of first card is heart = $P_{1}=\frac{13}{52}$

After replacement, the probability of second card is heart = $P_{2}=\frac{13}{52}$

after replacement, the probability of third card is heart = $P_{3}=\frac{13}{52}$

P = $\frac{13}{52}$ × $\frac{13}{52}$ × $\frac{13}{52}$

= $\frac{39}{156}$

= $\frac{1}{4}$

The probability of all three cards are hearts is $\frac{1}{4}$

Which of the following describes the domain of y = tan x, where n is any integer? A.x≠2nπ B. x≠π/2+nπ C. x≠nπ D.x≠nπ/2

pickupchik [31]

Y=tanx=sinx/cosx we cant divide by 0 so

cosx=0 would be a problm
cosx=0 when x=pi/2,3pi/2,...(2n+1)pi/2
(2n+1)pi/2=(2npi+pi)/2=2npi/2+pi/2=npi+pi/2
so its B
