A toy rocket is launched into the air at an initial velocity of 32 ft/sec, as shown on the graph below.
The function s(t) = - 16t2 + 32 + 128 gives the
height of the rocket (in feet) at time t (seconds).

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.
