Tests by an independent auditing firm show that 50% of students in a certain school think that Algebra is the best course they have ever taken. Use the entire line of random numbers below to estimate the probability that a randomly selected group of five students will contain at least 3 Algebra lovers. Let the digits 1-5 represent a student who thinks that Algebra is the best course.

Convert your probability answer to a whole number representing a percent.

anonymous · Answer

so they are already in the groups of 5

anonymous · Answer

so there are 10 altogether

anonymous · Answer

I'm still confused..

anonymous · Answer

now find how many of them have 3 or more numbers that are less than 6 ( meaning they like algebra ) 

= 5 altogether

anonymous · Answer

the first group, third group , fifth, eigth and tenth

anonymous · Answer

probability = 5/10 = 50%

anonymous · Answer

The eighth group shouldn't count because zero doesn't count as a student who likes algebra (only digits 1-5).  I get 4/10=40%
