Teaser Tuesday! April 15, 2014
Here's a couple teasers to get your mind off your soon-to-be-late taxes!
Note: If you could all please input your answers using the previously noted html code it will allow others to answer without having a spoiler. Also, in your answer, do not include any ' or " or it will not work properly.
Question 1
You can start flipping a coin, and at any time claim a prize in cents equal to the fraction of flips that came up heads. So, if you stop playing after getting 4 heads in 5 flips, you earn 80 cents. How much is the game worth?
Question 2
Create the number 24 using only these numbers once each: 3, 3, 7, 7. You may use only the following functions: +, -, *, /. This is not a trick question; for example, the answer does not involve a number system other than base 10 and does not allow for decimal points.
I remember playing this game in elementary school back in the 80s and I remember this particular one to be especially hard!
Good Luck!
should have mentioned decimal values are possible in intermediate calculations for q2 though.
I agree (^.^)Y
