5 Star QuestionsThese are to be answered within five minutes, with or without paper and pencil/pen, but without a calculator. is more often a prime number than a nonprime. true or False. Give reasons. #4. The probability of not getting atleast one 6 when a dice is cast 4 times is less than that of getting it. true of False? Explain. #5.

Re: 5 Star Questions#8. Inside a square of side 'a', another square is constructed with side a/2. Inside the smaller square, another square of side a/4 is constructed. This process in continued indefinitely. What is the area of all the squares so formed put together, including the parent square?

Re: 5 Star QuestionsVery well done, JaneFairfax and mathsyperson! JaneFairfax, wouldn't it be better if you explained how you got the solution? Good reasoning, mathsyperson! Character is who you are when no one is looking. #10 20070429 14:31:31
Re: 5 Star Questions#9. How many numbers ending in 3 between 1 and 1,000 are nonprimes? Character is who you are when no one is looking. #11 20070429 16:36:37
Re: 5 Star QuestionsWell, if I have counted correctly looking at this list, there should be 42 primes ending in 3 between 1 and 1000. Therefore the number of nonprimes ending in 3 between 1 and 1000 should be 100 − 42 = 58. #12 20070520 13:53:14
Re: 5 Star QuestionsJaneFairfax, you looked at the right list. Well done! Character is who you are when no one is looking. #13 20070520 14:11:10
Re: 5 Star Questionsthe first number is 2 ? I think it has many answers .. Last edited by Stanley_Marsh (20070520 14:15:50) Numbers are the essence of the Universe #15 20070520 19:43:56
Re: 5 Star QuestionsI agree with Stanley. You can craft a sequence to make any answer you want be right. Why did the vector cross the road? It wanted to be normal. #16 20070520 20:43:25

Re: 5 Star QuestionsThat's the answer I got as well, except that the left inequality should be strict. Why did the vector cross the road? It wanted to be normal. #19 20070524 18:19:25
