Objective question (only one correct). I. Which of the following has least mass? a. 1 mol of S b. 3 xx 10^(23) atom of C c. 2 g atom of nitrogen d. 7.0 g of Ag ii. The simplest formula of a compound containing 50% of element A (atomic mass 10) and 50% of element B (atomic mass 20) is: a. AB b. A_(2) B c. A_(2) B_(3) d. AB_(3)

Let A, B, C be three events. If the probability of occurring exactly one event out of A and B is 1 - a, out of B and C is 1 - 2a, out of C and A is 1 - a and that of occuring three events simultaneously is a^(2) , then prove that probability that at least one out of A, B, C will occur is greater than 1/2.

For three events A ,B and C ,P (Exactly one of A or B occurs) =P (Exactly one of B or C occurs) =P (Exactly one of C or A occurs) =1/4 and P (All the three events occur simultaneously) =1/6dot Then the probability that at least one of the events occurs, is : 7/(64) (2) 3/(16) (3) 7/(32) (4) 7/(16)

The probability of occurrence of an event A is 5/9 . The probability of non - occurrence of the event B is 5/11 . The probability that at least one of them will occur is :
