Explanation:

Use the identities ...

csc(x) = 1/sin(x)

cot(x) = cos(x)/sin(x)

$\csc(x)(\sin(x)+\cos(x))=1+\cot(x)\\\\\dfrac{1}{\sin(x)}(\sin(x)+\cos(x))=1+\cot(x)\\\\\dfrac{\sin(x)}{\sin(x)}+\dfrac{\cos(x)}{\sin(x)}=1+\cot(x)\\\\1+\cot(x)=1+\cot(x)$

In a class of 29 students, 19 are female and 14 have an A in the class. There are 8students who are male and do not have an A in

masya89 [10]

SOLUTION

The total number of females =

$19$

if 14 have an A in the class, the number of students without A is:

$29-14=15$

8 male students do not have an A, therefore the number of female students without an A is:

$15-8=7$

The probability that a student does not have an A given that the student is female can be calculated thus:

$\frac{\text{Total number of female students without an A}}{Total\text{ number of female students in the class}}$ $\frac{7}{19}$
