On the basis of mathematical theory, the chance of occurrence of any event is called theoretical probability.
For example if we toss a coin then the probability of a head and a tail is half half i.e 0.5.
But the probability calculated by repeated experiments and examine the outcomes are called experimental probability.
For example if we toss a coin 20 times and got 9 times head and 11 times head then the probabilities are given by
These probabilities are different what we got in case of theoretical probabilities.
Answer:
£1920
Step-by-step explanation:
The amount she spent in 2016 is 20% less than 2017. 20% less than is the same as 80% of the amount she spent in 2017. So, to find how much she spent in 2016, multiply 2400 by 0.80 (the decimal form of 80%):
2400 * 0.8 = 1920
Emily spent £1920 on holiday in 2016.
I hope this helps :)
Answer:
B
Step-by-step explanation:
When it's parallel that means it has the same slope. The slope of this equation is 1/2 therefore the answer is B
