There are 
of each suit in a deck of 
cards.
This means the probability of drawing a diamond card is 
. You can divide the numerator and denominator each by to simplify. 
Since there are the same number of clubs as there are diamonds, the probabilities are the same.
Yes because if you do 4÷16 it is .25.
Hope it helps. If it doesn't comment on the bottom. I'll try to explain it more
Answer:
y = -7.2x + 540
Step-by-step explanation:
to find the slope I used the x-and-y intercepts: (0, 540) and (75, 0)
slope = 540/-75 or -7.2
The quotient rule is
d(u/v) = (u dv - v du) / u2
d(u/v) can written as
d( u (1/v) )
Using the product rule and chain rule
d( u (1/v)) = u d(1/v) + (1/v) du
= u (-1/v2) dv + (!/v) du
= (u dv - v du) / u2
