You select a marble without looking and then put it back. If you do this 5 times, what is the best prediction possible for the number of times you will pick a pink marble?

You have a chance to get the pink marble at least once.

Since the ratio of pink marbles to other marbles is 1:5 meaning only 1 pink marble for every five you pick usually, the number of times you might pick a pink marble is 1 if you did it 5 times.

good job you smart son of a gun you are smarter that einstein. 7

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
