\textbf{Heya !}

<u>the denominators are equal, so subtracting these two fractions is a piece of cake:-</u>

<u />

<u />

<u />\sf{\cfrac{21}{15}-\cfrac{9}{15}}

\sf{\cfrac{21-9}{15}}

\sf{\cfrac{12}{15}}

<u>`hope it's helpful to u ~</u>

Korvikt [17]

Answer:

<em>(A) 560 students</em>

<em>(B) P = 0.41</em>

Step-by-step explanation:

<em>(Please check the attached picture for more details)</em>

As given, a survey of 1000 students found that:

41% of the surveyed students were freshmen

=> 1000 x 41/100 = 410 surveyed students were freshmen

31% were juniors

=> 1000 x 31/100 = 310 surveyed students were junior

67% of surveyed students lived on the college campus

=> 1000 x 67/100 = 670 surveyed students lived on the campus

<em>(A) 260 of the surveyed students were freshmen living on the campus</em>

=> A = 410 - 260 = 150 surveyed students were freshmen NOT living on the campus

=> B = 670 - 260 = 410 surveyed students were not freshmen living on the campus

=> The number of surveyed students who were either freshmen or living on the campus:

N = A + B = 150 + 410 = 560

<em>(B)  From a previous survey you know that of interviewed juniors, only 23% live on campus (we don't really need this)</em>

=>The probability a surveyed student is a junior or someone that lives on campus: P = (670 - 260)/1000 = 0.41

I hope this helps!
