P(r/w) is the probability of picking a red rose at first picking and a white rose at second picking.
P(w/r) is the probability of picking a white rose at first picking and a red rose at second picking.
P(r/w) =

=

P(w/r) =

×

=

Notice that the second fraction is out of 18 because the second picking of rose will be out of 18 since the first rose is not replaced.
P(r/w) equals to P(w/r)
Answer:
supplement: 137
complement: 47
Step-by-step explanation:
Supplement is two angles that equal 180, so just subtract 43 from 180.
complement is two angles that equal 90, so 90-43=47
The property used is: Multiplicative identity
Step-by-step explanation:
We need to identify the property in the equation : 
The property used is: Multiplicative identity
Multiplicative identity
The multiplicative identity property is defined as if you multiply a number by 1, the result of multiplication is that original number.
In the given expression
-3 is multiplied by 1 to get -3 so, multiplicative identity.
