Total members in the council (4 men, 6 women) = 10
One member is selected.
$rightwards double arrow$ $space straight n left parenthesis straight S right parenthesis space equals space straight C presuperscript 10 subscript 1 equals 10$
Event A: The member is to be a woman.
$rightwards double arrow$ $straight n left parenthesis straight A right parenthesis space equals space straight C presuperscript 6 subscript 1 equals 6$

Hence, $straight P left parenthesis straight A right parenthesis equals fraction numerator straight n left parenthesis straight A right parenthesis over denominator straight n left parenthesis straight S right parenthesis end fraction equals 6 over 10 equals 3 over 5$
