Amagician shuffles a standard deck of playing cards and allows an audience member to pull out a card, look at it, and replace it in the deck. four additional people do the same. find the probability that of the 5 cards drawn, at least 1 is a face card. (round your answer to one decimal place.)

Step-by-step explanation:

There are 12 face cards (4 kings, 4 queens, and 4 jacks).

That means 40 cards are not face cards.

The probability that at least 1 of the 5 cards drawn is a face card is equal to 1 minus the probability that all of the cards were not face cards.

P(at least 1) = 1 − P(no face cards)

P = 1 − (40/52)⁵

P = 0.731

The probability is 73.1%.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
