Question

Tangerine farms claims only 4% of their oranges will contain less than 5 ounces of juice. Tropicana decides to verify their claim by taking a random sample of 500 oranges and counting how many contain less than 5 ounces of juice. 30 of the 500 oranges sampled contained less than 5 ounces. If tangerine claim is true that only 4% of oranges containing less than 5 ounces of juice what is the probability of getting 30 or more oranges containing less than 5 ounces in a sample of 500.
