OA E 200x1 Power of 1 can be anything, if its 6 then it satisfies B otherwise not

there 5 balls, 2 black, 1 blue, 1 yellow, 1 pinc. number of arrangements so that no two black ball come together a. 12 b. 24 c. 36 d. 48 e. 60

m^a * n^b = 200, all +ve integers. a+b = ? A. a > b B. a * b =6

D 1. if y > 0, and -2x is more than 3y, x need to be negative 2. 2x+3y=20 >> 15y= 60-6x now -2x>3y -10x> 15y -10x> 60-6x x

A forbids to

A set X has integers from 1 to 10 and another set Y has integers 5 greater than or 5 less than the value of elements in X. At most, how many different elements are there in set Y? A. 20 B. 30 C. 15 D. 40 E. 20 please explain.

thank tarkumar

OA is C

what is the probability that event x or event y or both will happen? a. P(x)= 0.7 b. P(y)= 0.3 please explain.

OA is 36 @tarkumar can you please elaborate the concept ..."No of possible ways of ararnging the five letters with no restriction : 5!/2!=60"

In how many ways can m,n,o,o, and p be arranged to make five letter code in such a way that two o are not coming next to each other? 1. 72 2. 84 3. 50 4. 48 5. 36

imho B

imho E

imho A

imho A B- 'could be' changes the meaning......as if its not persistent so far and how its going to be in the future. C - present perfect tense is required.....its started long back and its still.... E - awkward
