A quiz is made up of 5 questions, all of which are true or false questions. Justina wants to estimate the probability that a student who guesses on all the questions will answer more than 3 correctly.

She flips a coin 5 times, letting H represent a correct guess and T represent an incorrect guess. She repeats this process for a total of 15 trials.The results are shown in the table.

HHTTT THTTT THTHH TTTTH HTHHH
THHTT HHTHT HTHHT THTHH HHTHH
TTHHT HHHTH HHHTT THHHT HHTTT

Drag and drop the estimated probability, using this simulation.

the anwser is b guys

Using it's concept, it is found that the probability of guessing correctly on more than 3 out of 5 true-false questions is given by:

B. 1/5

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

  • 15 simulations were made.
  • Of those, 3 resulted on more than 3 out of 5 true-false questions.

Hence:

[tex]p = \frac{3}{15} = \frac{1}{5}[/tex]

Hence option B is correct.
