Answer
a. $0.047$
b. $0.065$
c. $0.821$
Work Step by Step
$p=0.26, n=12$
a. Exactly 6 couples will have a destination wedding
$P(X=6)=_{12}C_60.26^60.74^6=0.047$
b. At least 6 couples will have a destination wedding
$P(X\geq6)=1-P(X\leq5)=0.065$
c. Fewer than 5 couples will have a destination wedding
$P(X\leq4)=0.821$
