Math probability question
posted by Bob .
a spinner is divided into three areas x,y,z. the measure of angle a is 90 degrees, angle b is 120 degrees and angle c is 150 degrees.
If the spinner is spun once, find the probabliity that it will land in
1) area X
2) area y
3) area z

The probability is the area of choice divided by total area.
2) Pr(y)=areay/totalarea=120/360=1/3 
what is the probability 1.4
