Adeck of cards has three yellow cards and five green cards. one green card is drawn from the deck and not replaced. one more card is randomly drawn. find the probability that the second card is yellow.

a. 3/8
b. 3/7
c. 15/56

Option B. 3/7

Step-by-step explanation:

A deck of cards contains yellow cards = 3 and green cards = 5

So total numbers of cards = 3+5 = 8

Now one green card is drawn so numbers of cards left with us = 8-1 = 7

This is true only when this green card was not replaced.

Now the probability to draw second card with color yellow = yellow cards/Total numbers of cards = 3/7

So the answer is Option B. 3/7

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
