In a certain Algebra 2 class of 26 students, 10 of them play basketball and 5 of them play baseball. There are 3 students who play both sports. What is the probability that
a student chosen randomly from the class plays basketball or baseball?

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
