Question

If the next two Junior Athletics events are sold out, the new table will look like this: Event 1 Event 2 Event 3 Event 4 Event 5 Event 6 Event 7 Junior Athletics Sold Out Sold Out Not Sold Out Not Sold Out Sold Out Sold Out Sold Out What is the new probability of the event being sold out? Give your answer as a fraction.

Answer 1

0.7 is the new probability of the event being sold out given that total number of events is 7 and 5 events are sold out. This can be obtained by using the formula for probability.

Find the new probability of the event being sold out:

Probability is the chance of occurrence of an event.

⇒ The formula for finding probability,

Probability = $\frac{Number\ of\ favourable\ outcomes}{Total\ number\ of\ outcomes}$

Here it is given in the question that,

• Total number of outcomes = Total number of events = 7

• Number of events sold out = 5

• Number of events not sold out = 2

Therefore by using the formula of probability we get,

⇒ Probability (Junior Athletics being sold out) = $\frac{Number\ of\ favourable\ outcomes}{Total\ number\ of\ outcomes}$

Probability (Junior Athletics being sold out) = $\frac{Number\ of\ events\ sold\ out}{Total\ number\ of\ events}$

Probability (Junior Athletics being sold out) = 5/7

⇒ Probability (Junior Athletics being sold out) = 0.7

Hence 0.7 is the new probability of the event being sold out given that total number of events is 7 and 5 events are sold out.
