Mrs. Sue please help!

A true-false test has 12 questions. What is the probability of guessing the correct answers to all of the questions? (1 point)
1 over 4096
1 over 144
one over twenty four
1over14

To calculate the probability of guessing all the correct answers on a true-false test, we need to determine the total number of possible outcomes and the number of favorable outcomes.

In this case, each question has two possible answers (true or false). Therefore, the total number of possible outcomes for all 12 questions is 2 raised to the power of 12 (2^12).

To find the number of favorable outcomes, we are interested in the scenario where we guess the correct answer for all 12 questions. Since there are only two options for each question, there is only one favorable outcome.

Now, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes:

Probability = Number of favorable outcomes / Total number of possible outcomes
= 1 / 2^12
= 1 / 4096

Hence, the probability of guessing all the correct answers to all 12 questions on a true-false test is 1 over 4096.

what is .5^12 ?

Put this in your google search engine
1/.5^12=

that number is how many possible ways there is to choose 12 times.

so a is the answer?

Isn't that what the Google calculator showed you?

yes, it is, a is the right answer.

thank you so so so so sosososo much
