Answer:
a) 
b) 
Step-by-step explanation:
<u>Coterminal angles</u> have the same terminal sides in standard position.
a) To find an angle between 
and 
, that is coterminal with 
, we keep adding multiples of until we get an angle within the specified range.
.
In some cases you would have to subtract in order to get the specified angle. That is when the angle given is positive.
b) This time we want to find an that coterminal with radians.
We keep subtracting multiples of 
until we get an angle measure within the specified range.
Do you have a picture of the problem
In the usual spinner that we have, the circular figure is divided into 8 equal parts. Each of which is numbered from 1 to 8. There are two of these numbers that are multiple of 4 (4 and 8). Now, the probability that the spinner will land on a multiple of 4 is equal to 2/8 or also equal to 1/4 or 0.25.
We are given with
95 pink rubber bands
90 brown rubber bands
The probability of selecting a pink rubber band is
P = 95 / (95 + 90) = 19/37
The probability of selecting a brown rubber band is
P = 90 / (95 + 90) = 18/37
