You have a standard deck of 52 playing cards (13 of each suit). you draw a hand of the top 17 of them. spades are one of the four suits. what is the expected value of the number of spades you draw?

The expected value of the number of spades are = 4.25

Step-by-step explanation:

As per the question,

W know that in a standard deck of 52 playing card, there are 4 suits, and each suit have 13 playing card.

Since, we know that

Therefore,

Probability of any random card being a spade is

So the expected number of spades we draw are

Hence, the expected value of the number of spades are = 4.25

answer: the answer is 127 degrees

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
