Q1) You can use Lagrange's mean Value theorem...velocity is dx/dt=f'(x)...now use LMVt within the interval and u will find dx/dt=5 atleast once..hence option d.
Q41) P(A intersection B)=P(A)*P(B) where nither P(A) nor P(B)=0 simultaneously according to the definition of independence of events..so P(B) cannot be zero neither can P(A) be so at the same time.
Q50) Point probability in a continuous distribution is zero but not undefined or indeterminate.
