You have to subtract the 3 officers who can not be chosen from all 35 members. So the probability is 1/32 because 35/3=32
Answer:
T > -9/28
Step-by-step explanation:
A quadratic has two real solutions when the discriminant (b² - 4ac) is positive.
b² - 4ac > 0
3² - 4(T)(-7) > 0
9 + 28T > 0
28T > -9
T > -9/28
