A multiple choice question has `n` options, of whlch only one is correct. If a student does home work, then it is sure to identify the correct answer, otherwise answer is choosen at random. Let `E` be the event that student does home work with `P(E)=p` and `F` be the event that student answers question correctly
If `n=5,p=0.75` the value of `P(E//F)gelamda`, then `lamda` can be

A

There are 5 questions in a multiple choice examination in which each question has 3 possible answers.Find the probability that a student gives 4 correct answers by guess only.

In answering a question on a multiple choice test, a student either knows the answer or guesses. Let 3/5 be the probability that he knows the answer and 2/5 be the probability that he guesses. Assuming that a student who guesses at the answer will be correct with probability 1/3 , what is the probability that the student knows the answer given that he answered it correctly

In an examination a student has to answer 4 questions out of 5 questions; questions 1 and 2 are however compulsory. Determine the number f ways n which the student can make the choice.

Each question has four choices a, b, c, and d, out of which only one is correct. Each question contains STATEMENT 1 and STATEMENT 2. Both the statements are TRUE and statement 2 is the correct explanation of Statement 1. Both the statements are TRUE but Statement 2 is NOT the correct explanation of Statement 1. Statement 1 is TRUE and Statement 2 is FALSE. Statement 1 is FALSE and Statement 2 is TRUE. Statement 1: For events Aa n dB of sample space if P(A/B)geqP(A) , then P(B/A)geqP(B)dot Statement 2: P(A/B)=(P(AnnB))/(P(B)) , (P(B)!=0)dot

Comprehension given below is followed by some multiple choice questions. Each question has one correct option. Choose the correct option. In the modern periodic table, elements are arranged in order of increasing atomic numbers which is related to the electronic configuration. Depending upon the type of orbitals receiving the last electron, the elements in the periodic table have been divided into four blocks, viz s, p, d and f. The modern periodic table consists of 7 periods and 18 groups. Each, period begins with the filling of a new energy shell. In accordance with the Aufbau principle, the seven periods (1 to 7) have 2, 8, 8, 18, 18, 32 and 32 elements respectively. The seventh period is still incomplete. To avoid the periodic table being too long, the two series of f-block elements, called lanthonoids and actinoids are placed at the bottom of the main body of the periodic table (ii) The last element of the p-block in 6th period is represented by the outermost electronic configuration.
