Afive question multiple choice quiz has five choices for each answer. use the random number table provided, with 0's representing incorrect answers, and 1's representing correct answers, to answer the following question. what is the probability of correctly guessing at random exactly one answer? round to the nearest whole number.

The correct answer is:  Option: b

              b.  15%

The probability of correctly guessing at random exactly one answer i.e. we are asked to find the probability of outcome with exactly one " 1 "

Such outcomes are:

{ 10000 , 01000 , 10000 }

i.e. there are exactly three outcomes.

Total number of outcomes= 20

Hence, the probability is:

Hence, the probability of correctly guessing exactly one answer is:

                          15%
