Your teacher divides the class into two groups of the same size by picking names at random from the class, and you will be in group 1? A. impossible B. unlikely C. as likely as not D. Likely E. certain

Answers

Answer:

C. as likely as not

Step-by-step explanation:

The teacher makes two groups with the same number and divides the student at random. The two groups have equal size, so the chance for someone to get picked into group 1 is 100%/2= 50%. The chance for someone to get picked into group 2 will be also 100%/2= 50%

The chance to get picked to be in group 1(50%) is the same as the chance to NOT get picked into group 1(50%). The word to explain this chance will be "as likely as not".
