Acard is picked at a random from a standard deck of 52 what is the probability of picking a face card

Total cards in a deck=52

Face cards =12

So probability of picking a face card is 12/52=3/13

Step-by-step explanation:

Usually there are 12 face cards in a group, so that would be 12/52 -- but wait! You can simplify, always. check. for. simplifying. possibilities.

Usually in an answer they will include both simplified, and not simplified. Believe it or not, usually they ask for the simplified. Make sure you read carefully.

The probability is 3/13

Step-by-step explanation:

There are 12 face cards in a deck

simplify 12/52

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
