Answer:

The probability of the complement of the original event is 5/7.

Step-by-step explanation:

The probability of the complement of an event is 1 less the probability of the event, so

We get:  1 - 2/7, or 5/7

The probability of the complement of the original event is 5/7.

Note that  5/7  and 2/7  add up  to 7/7, or 1.

I don't know whats wrong, please help. It is the exact formula.
const2013 [10]
The formula for circumference is 2\pir, where r is equal to radius.
It states to use 3.142 for pi
It also provides you with the diameter, not the radius, so you have to divide it by two to get 4.5
2*3.142*4.5= approximately 28.278 or 28.3

Please I really need help on this matter question
Katarina [22]
The answer should be 1. Keep in mind that all cubic curves will always have at least 1 real zero. The embedded image is a graph of y=(x+8)³+9


The second answer should be y=xx^{4}-6xx^{3}+6xx^{2}-6x+5 (the last answer choice), as seen by the second image.
