Two of the cards of an ordinary deck of 52 cards are lost. what is the probability that a random card drawn from this (defective) deck is a spade? (show your work! define any events that you use, and be clear and neat! )

0.72

Step-by-step explanation:

Given :Two of the cards of an ordinary deck of 52 cards are lost.

To Find : What is the probability that a random card drawn from this (defective) deck is a spade?

Solution:

Total number of cards = 52

2 cards are lost

Remaining cards = 50

When no spade card is lost

So, No. of spade cards = 13

Total cards = 50

So, probability of getting spade =

When 1 spade card is lost

So, No. of spade cards = 12

Total cards = 50

So, probability of getting spade =

When 2 spade cards are lost

So, No. of spade cards = 11

Total cards = 50

So, probability of getting spade =

So, The he probability that a random card drawn from this (defective) deck is a spade =  

                  =  

                  =  [tex]0.72/tex]

Hence the probability that a random card drawn from this (defective) deck is a spade is 0.72

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
