Answer: The  experimental probability that she will roll an even number= \frac{1}{2}


Step-by-step explanation:

We know that the probability for any event is given by6;-

\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}

In a dice, the total even numbers (2,4,6)= 3

Therefore, the probability that she will roll an even number will be given by:-

\text{Probability}=\frac{\text{3}}{\text{6}}=\frac{1}{2}

Hence, The  experimental probability that she will roll an even number= \frac{1}{2}

11111nata11111 [884]

Answer:

Required probability is 0.784 .

Step-by-step explanation:

We are given that in a large statistics course, 74% of the students passed the first exam, 72% of the students pass the second exam, and 58% of the students passed both exams.

Let Probability that the students passed the first exam = P(F) = 0.74

     Probability that the students passed the second exam = P(S) = 0.72

     Probability that the students passed both exams = P(F \bigcap S) = 0.58

Now, if the student passed the first exam, probability that he passed the second exam is given by the conditional probability of P(S/F) ;

As we know that conditional probability, P(A/B) = \frac{P(A\bigcap B)}{P(B) }

Similarly, P(S/F) = \frac{P(S\bigcap F)}{P(F) } = \frac{P(F\bigcap S)}{P(F) }  {As P(F \bigcap S) is same as P(S \bigcap F) }

                          = \frac{0.58}{0.74} = 0.784

Therefore, probability that he passed the second exam is 0.784 .

Given the exponential growth of scientific knowledge,
MAXImum [283]

Given the exponential growth of scientific knowledge, medicine is far less (C) vulnerable to unsubstantiated fads than it used to be; its record of folly, however, remains an undeniable embarrassment.

<h3>What is scientific knowledge?</h3>
  • Knowledge can be defined as factual awareness or practical skills, but it can also refer to familiarity with objects or situations.
  • Knowledge of facts, also known as propositional knowledge, is frequently defined as the true belief that differs from opinion or guesswork due to justification.
  • Scientific knowledge is a generalized body of laws and theories developed through the scientific method to explain a phenomenon or behavior of interest.
  • Theories are systematic explanations of the underlying phenomenon or behavior, whereas laws are observed patterns of phenomena or behaviors.

To find the correct option:

  • Option (C) is the correct option because, according to the sentence comparison of medical sciences to scientific knowledge growth, its foolish researches lead to embarrassment.
  • As a result, option (C) is the correct answer.
  • Other options do not correspond to the meaning of the given sentence.

Therefore, given the exponential growth of scientific knowledge, medicine is far less (C) vulnerable to unsubstantiated fads than it used to be; its record of folly, however, remains an undeniable embarrassment.
