Refer to a standard deck of playing cards. Assume 5 cards are randomly chosen from the deck. How many hands contain 4 aces?

Setler79 [48]

There would be 0.07923 probability to get 4 aces.

<h3>What is probability ?</h3>

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Total number of cards in deck = 52

Total number of aces = 4

When 5 cards are chosen randomly,

The probability to get 4 aces

= 1/52+1/51+1/50+1/49+0

Since, at 5th time there will be no ace remains, so probability would be 0.

= 0.01923+0.01960+0.0200+0.0204

=0.07923

Please help me asap I will extra points show work it is surface area of prisms thank you

lutik1710 [3]

Okay, the easiest way (I personally) find surface area is to find the area of each face [L x W (OR H)] and then add all of the areas together.

Question 1) The Area of 1 of the faces is 4, because 2 x 2 is 4. Since there is 6 faces, do 6 times 4, or $24^{2}$ feet in total.
