A standard deck of playing cards has 52 cards: 13 spades, 13 clubs, 13 hearts, and 13 diamonds. What is the probability of drawi
Vaselesa [24]

13 spades, 52 cards total

probability of drawing a single spade = 13/52 = 1/4

If we replace that card, then the probability of drawing of drawing a spade is still 1/4 as nothing has changed

Overall, the probability of getting two spades in a row is (1/4)*(1/4) = 1/16

note: the two events are independent because of the replacement happening

---------

The answer as a fraction is 1/16

As a decimal, that would be 0.0625 which converts to 6.25%

I need help with this also. (homework due tomorrow)
Alla [95]

Answer:

Using Pyhagoras theoram,

(H)^2 = (B)^2 + (P)^2

B = 13 in

P = 5 in

(h)^{2}  = (13)^{2}  +  {(5)}^{2}  \\ =  >  (h)^{2}  =  169 + 25 \\  =  > (h)^{2}  = 194 \\  =  > h =  \sqrt{194}  \\  =  > h = 13.92

Hence, the missing side is 13.92 inhes.
