Acard is chosen at random from a deck of 52 cards. it is replaced and a second card is chosen. what is the probability of choosing a king and an ace?

Step-by-step explanation:

Total cards = 52

Total ace = 4

So probability of getting ace on first draw =

Now the card is replaced .

So, Total cards = 52

Total kings = 4

So probability of getting kings on second draw =

So,  the probability of choosing a king and an ace:

=  

=  

Hence the probability of choosing a king and an ace is  

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

25% is the answer
