It means that you take the number and multiply it by itself the amount of what the small number is. for example, if i have 7 with a 2 above it i need to multiply it by itself twice so

7x7=49

if it has a three above it i need to multiply it by itself 3 times

7x7x7= 343

hope this helps and feel free to ask further questions

ex:

2²= 2×2

2³= 2×2×2

If the probability of an event is what is the probability of the event not happening?20/69Write your answer as a simplified frac

Vilka [71]

If an event has a probability P of happening, then there is a probability of (1-P) of the event not happening.

In this case the probability of the event is p=20/69.

Then, the probability of the event not happening is:

$P(\text{not happening})=1-p=1-\frac{20}{69}=\frac{69-20}{69}=\frac{49}{69}$

Answer: the probability of the event not happening is 49/69.
