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: There are 7 tadpoles which Jack can catch.
Step-by-step explanation:
Since we have given that
Let the number of tadpoles Jack has be x
Let the number of tadpoles Jill has be 9(x+3)
According to question,
Hence, there are 7 tadpoles which Jack can catch.
Answer:
120/97
Step-by-step explanation:
When you're turning a mixed fraction into an improper fraction, you keep the denominator (bottem number) the same, but you times the numerator (top number) by the whole number (non-fraction number/left number)
6 * 20 = 120
Therefore it should be 120/97
This can not be simplified though (if I recall)
<span>5 (9/12 - 1/4) + 0.5
</span><span>5 (9/12 - 3/12) + 0.5
5 (6/12) </span><span> + 0.5

Answer:
Step-by-step explanation:
Let the price is x.
<u>With 17% discount it becomes:</u>
- x - 17% of x =
- x - 0.17x =
- 0.83x
The number we need is 0.83
