3 numbers are randomly selected, with replacement, from the set of integers {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. If the first number selected is w, the second number selected is x, and the third number is y, what is the probability that w < x < y ?

Solution: Total possible ways = 10*10*10 = 1000 Case1: w=0. if x = 1, then y can have 8 ways. if x =2 , then y can have 7 ways and so on. So, no. of ways = 8+7+..+1 Case2 : w=1. if x = 2, then y can have 7 ways. if x =3 , then y can have 6 ways and so on. So, no. of ways = 7+6 +..+1 There will be 8 cases in this way an...

A crow leaves its nest, and flies back and forth from its nest to a nearby ditch to gather worms. The distance between the nest and the ditch is 400 meters. In one and a half hours, the crow manages to bring worms to its nest 15 times. What is the speed of the crow in kilometers per hour?
[ "A)2", "B)4", "C)6", "D)8" ]
D
The distance between the nest and the ditch is 400 meters. 15 times mean = A crow leaves its nest, and flies back ( going and coming back) i.e. 2 times we get total 30 rounds. So the distance is 30 * 400 = 12000. D = ST 12000/1.5 = T , I think we can take 12000 meters as 12km, then only we get T = 8.( 1000 meters = 1 k...

All of the students of Music High School are in the band, the orchestra, or both. 80 percent of the students are in only one group. There are 136 students in the band. If 60 percent of the students are in the band only, how many students are in the orchestra only?
[ "A)33", "B)39", "C)34", "D)42" ]
