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.
<h3>Find the new probability of the event being sold out:</h3>
Probability is the chance of occurrence of an event.
⇒ The formula for finding probability,
Probability =
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) = 
Probability (Junior Athletics being sold out) = 
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.

Answer:
It is a singular matrix system.
Step-by-step explanation:
A column of all zeros in a matrices says that the variable associated with that column has no effect on the output.
For example If the first column of a matrix consists of zeros, this means that the coefficient of the first variable is zero in every equation in the system . This means that if there is any solution at all, then there must be an infinite number of them, since you can set that first variable to any value at all and still satisfy all of the equations.
