Answer:

The right solution is "0.5545".

Explanation:

According to the question,

The probability of having 6 or 7 males will be:

=
$P(6 \ males)+ P(7 \ males)$

=
(15_C_6* 13_C_6)/(28_C_(12)) + (15_C_7* 13_C_5)/(28_C_(12))

=
(5005* 1716+6435* 1287)/(30421755)

=
(16870425)/(30421755)

=
0.5545
