On a US flag that is 19 ft by 10 ft, the union is 7 5/8 ft by 5 3/8 ft. For each question, first estimate the answer and then compute the actual percentage. What percentage of the flag is taken up by the union?

The answer is 1 over 10.there is a total of 20 bottles, and 4 of them are purple, so there is a 1 in 5 chance of him picking a purple bottle (4/10 = 1/5)when flipping a coin, there are two outcomes, and heads is one, so 1/2.with these two probabilities, we multiply them, so (1/5)*(1/2) = (1/10)
