With a typical 52-card deck that has 4 jacks, Margaret is playing a game. The game is initiated by the first player to choose a jack. When choosing first, Margaret's probability of selecting Jack is 1/13.

The same will occur since probability will be determined using the formula necessary outcome divided by total outcome.

Here, the total number of cards in the deck (total outcome) equals 52.

Given that Margaret can select any of the four jacks, the necessary result (number of jacks) is 4.

Probability is 4/52, or 1 by 13, which is the required probability for the question.

The professor informs the class that there will be a test next week. what is the probability that a randomly selected student st
marusya05 [52]

The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.

<h3>How to calculate the probability?</h3>

In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.

  • Let S represent studied for.
  • Let B represent a score of B or higher grade

Therefore, we need to find P(S|B):

S|B = \frac{B|S \times S}{B|S \times S\; +\; B|S' \times S'} \\\\S|B = \frac{0.55 \times 0.6}{0.55 \times 0.6 \;+ \;0.2 \times 0.4}\\\\S|B =\frac{0.33}{0.33 + 0.08} \\\\S|B =\frac{0.33}{0.41}

S|B = 0.80.

<u>Complete Question:</u>

At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
