Hey folks, I've hit my very weak spot. Probability and Statistics

I have a problem here, and I REALLY want to use but it's not giving me the right answer, and I've tried using and all to no avail. I have the correct answer to reference, but I cannot for the life of me seem to get to it, any help would be appreciated!

The problem is this:

Right off the bat I think and the first step to me seems like it should be using because of the wordsIn one town, 74% of the homes have satellite dishes. A pollster randomly sampled 50 homeowners from the town. What is the probability that at least 42 of them have satellite dishes? Round your answer to 4 decimal places.at least, rather thanexactly.

This isn't working at all, the correct answer to the problem is .

Again, any help or clarification at all would be great, thanks!
