Question

what is the probability of an impossible event?
a. one \t\t\tc. zero
b. a number larger than one \t\td. one-half

please select the best answer from the choices provided

○ a
○ b
○ c
○ d

Explanation:

In probability theory, the probability of an event ranges from 0 to 1. An impossible event is one that cannot occur, so its probability is 0. Option a (one) is the probability of a certain event. Option b (a number larger than one) is invalid as probability can't exceed 1. Option d (one - half) is the probability of an event with a 50% chance of occurring, not an impossible event.

Answer:

C. zero
