A true-false test consists of 11 questions. a) in how many ways can the test be completed, selecting true or false for each question? b) what is the probability that a test is randomly answered perfectly? a) in how many ways can the test be completed, selecting true or false for each question? the test can be completed in nothing ways. (type a whole number.) b) what is the probability that a test is randomly answered perfectly? the probability is nothing. g

(a) 2048

(b) .

Step-by-step explanation:

(a)

Total number of questions = 11

Each equation has two possible answers (either true or false).

We need to find the total number of ways in which the test can be completed.

Therefore the total possible ways to complete the test is 2048.

(b)

We need to find the probability that a test is randomly answered perfectly.

Total Favorable outcomes = 1

Total possible ways = 2048

Therefore the probability that a test is randomly answered perfectly is .
