The quantity of the likelihoods of all specific events in an experiment is 11.

  1. The probability of an event is inordinate than or equal to and less than or

is equal to _____.


The probability of an event is greater than or equal to 00 and less than or equal to 11.

  1. Which of the following experiments has equally likely outcomes? To explain.
  2. A driver tries to start a car. The car does not start or start.
