2.	Which of the following is the correct equation for the theoretical probability of an event A ?

P (A)

= \frac{number of trials}{number of times the event occurs}

P (A)

= \frac{number of times the event occurs}{number of trials}

P (A) = \frac{n}{N},

where n is the number of outcomes in the event and N is the number of outcomes in the sample space.

P (A) = \frac{n}{N},

where n is the number of outcomes in the sample space and N is the number of outcomes in the event.

Answer: $P (A) = \frac{n}{N},$ where n is the number of outcomes in the event and N is the number of outcomes in the sample space.

3.	Which of the following is the correct equation for the experimental probability of an event A ?

P (A)

= \frac{number of trials}{number of times the event occurs}

P (A)

= \frac{number of times the event occurs}{number of trials}

P (A) = \frac{n}{N},

where n is the number of outcomes in the event and N is the number of outcomes in the sample space.

P (A) = \frac{n}{N},

where n is the number of outcomes in the sample space and N is the number of outcomes in the event.

Answer: $P (A)$ $= \frac{number of times the event occurs}{number of trials}$
