Random sample, $np \geq 10$ and $n(1-p) \geq 10$ , so yes, both conditions were satisfied.

Step-by-step explanation:

60% of the people in a certain midwest city who are responsible for preparing the evening meal have no idea what they are going to prepare as late as 4PM in the afternoon.

This means that $p = 0.6$

A recent survey was conducted from 1000 of these individuals.

This means that $n = 1000$

Also, a random sample, so the first condition was satisfied.

The sample size must be large (so that at least 10 or more successes and failures).

$np = 1000*0.6 = 600 \geq 10$

$n(1-p) = 1000*0.4 = 400 \geq 10$

So yes, both conditions were met.
