Question

Suppose That on a particular multiple-choice question 95% of the students answer correctly what is the probability that a randomly selected student answered the question incorrectly.

Answer 1

Answer:

P(Incorrectly)=5%

Step-by-step explanation:

-The probability of answering correctly is 95%=0.95

-The probability of answering incorrectly is one minus the probability of answering correctly:

$P(Incorrect)=1-P(correct)\\\\=1-0.95\\\\=0.05$

Hence, the probability of answering incorrectly is 0.05 or 5%
