decide'. If a student is chosen at
random , what is the chance that the
student did not say "no"? *​

Answer 1

The chance that the student chosen at random did not say "no" is 0.47

Step-by-step explanation:

Given:

53% students said "no" and 20% students said yes in a survey, rest were undecided

To find out:

The probability that a student picked at random did not say no.

Solution:

Students that said "no" = 53%

Therefore, probability that a student chosen at random said "no" = 53/100 = 0.53

Thus, the probability that a student chosen at random did not say "no" = 1 - 0.53 = 0.47
