Suppose you take a 12-question true or false quiz by guessing each answer. Use the binomial table to find the probability of guessing 6 or more questions correctly.

0.6127 = 61.27% probability of guessing 6 or more questions correctly.

Step-by-step explanation:

For each question, there are only two possible outcomes. Either you guess the correct answer, or you do not. The probability of guessing the correct answer of a question is independent of other questions. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

12 questions:

This means that

True-false:

Two options, one of which is correct. So

Find the probability of guessing 6 or more questions correctly.

In which

0.6127 = 61.27% probability of guessing 6 or more questions correctly.

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
