In Evan's senior class of 240 students, 85% are planning to attend college after graduation. What is the probability that a senior is chosen at random not planning to attend college after graduation?

For this case we want to find the probability that a senior is chosen at random not planning to attend college after graduation so then we can use the complement rule given by:

Where A is the vent of interest and replacing we got:

So then the probability that a senior is chosen at random not planning to attend college after graduation is 0.15 or 15%

Step-by-step explanation:

For this case we know that the sample size if n =240 and we also know that the probability that in the Evan's class the any student are planeed to attend collge after graduation is:

For this case we want to find the probability that a senior is chosen at random not planning to attend college after graduation so then we can use the complement rule given by:

Where A is the vent of interest and replacing we got:

So then the probability that a senior is chosen at random not planning to attend college after graduation is 0.15 or 15%

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

where's the diagram?
