Answer:

P(Incorrectly)=5%

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%
