  1. A typical day is 24 hours = 1440 minutes = 86,400 seconds.
    1. What are the ODDS you will land on 7:15 either AM or PM (twice in a day)?

                  b. What is the PROBABILITY you will land on 7:15 either AM or PM (twice in a day)?

Answer #1

We know that the total number of seconds in a day, TS= 86400

We know that the total number of minutes in a day, TM= 1440

a.

Odds that we land on 7:15 am or 7:15 pm= probability of falling on 7:15 am or pm / probability of not falling on 7:!5 am or pm

= (2/1440) / (1438/1440)

= 2/1438

= 0.001390821

b.

Probability of falling on 7:15 am or pm

= 2/1440

= 0.001388889

We are using 2 in the denominator because 7:15 occurs for 2 minutes (7:15 am and 7:15 pm) in an entire day out of the total 1440 minutes.

(Thus, the odds are higher than the probability)
