Picking a 7 from a standard deck of 52 cards. a standard deck includes 4 cards of each number from 2 to 10?

1/13

Step-by-step explanation:

I'm assuming you need the probability of choosing a 7 when pulling one card from a standard deck of playing cards.

There are four 7's in a deck of 52 cards.

Probability = (number of desired outcomes)/(number of possible outcomes)

The number of desired outcomes is 4 because there are 4 chances of pulling a 7 from a deck when choosing one card.

The total number of possible outcomes is 52 because there are 52 different cards to choose from when choosing one card.

So the probability is

P(7) = 4/52

P(7) = 1/13

1/13

Step-by-step explanation:

i did the work in my head.

i do not know this sorry : (

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
