yeah that make sense.thanks

FOR DI the ans is 7 For speed problem, i think your formula should be applied when a vehicle goes a certain distance and then returns in the same direction. but however, your ans for the speed problem is correct.

anyone please? i have my exam on 12th december.

in actual test it is most likely that they will give you the clue where the correct answer is? Like,say, in paragraph 5 what ............the author mean? Hope this help.

Q. Find the least positive integer with four different prime factors, each greater than 2.

Distinct means not alike; different in nature or quality.

1. Mike,Allen and Tracy each try independently to solve a question.if their individual probabilities for success are 1/4, 1/2, 5/8, respectively, what is the probability that mike and allen, but not tracy,will solve the question? 2. If a coin is to be tossed three times , what is the probability that on at least on of the tosses the coin will turn up tails? 3. When tossed, a certain coin has equal probability of landing on either side.If the coin is tossed 3 times, what is the probability that it will land on the same side each time? 4. From a group of 3 boys and 3 girls, 4 children are to be randomly selected, what is the probability that equal number of boys and girls will be selected? 5.If an integer n is to be chosen at random from the integers 1 to 96,inclusive,what is the probability that n(n+1)(n+2) will be divisible by 8? 6. There are 8 magazines lying on a table; 4 are fashion magazines and the other 4 are sports magazines.If 3 magazines are to be selected at random from the 8 magazines, what is the probability that at least one of the fashion magazines will be selected?

Q. the probability that a student is absent and that is friday is 0.03.Since there are 5 school days in a week,the probability that is friday is 0.2.what is the probability that a student is absent given that today is friday?

thanks jess_john.Well understood.

Q. A coin is tossed three times, find the probability of 1) getting exactly 2 heads 2)At least two heads 3) more than two heads?

Col A: sqrt11+sqrt17 Col B: sqrt14+sqrt14

7% of those asked were in favor of at least one of the 3 proposals what percentage of those asked favored more than one of three proposals? for the second problem i cannot understand this lines.

i like the approach of Retake_GMAT.and it was mine too. the ans should be C.

3^k, here k indicates the how many three are there.right? now, 1 to 30 inclusive, how many 3 are there so that the product will be a multiple of 3^k and vice versa. how many 3 are there in the product of the integers from 1 to 30, inclusive.lets see. 3*6(i.e,3*2)*9(i.e,3*3)*12(i.e,3*4)*15(i.e,3*5)*18(i.e,3*3*2)*21(i.e,3*3*2)*24(i.e,3*8)*27(i.e,3*3*3)*30(i.e,3*10) we dont use the other integers coz they are useless for this problem and the factor is 3^k so we only consider that numbers which is a multiple of 3. so the ans should be 14.

1. 20% of the families in a city have a car, 30% have a refrigerator and 40% have a TV set, Again 10% have a car and a refrigerator, 15% have a refrigerator and a TV and 8% have a car and TV, 5% of the families have all the three items. What percent of families have none of the three items? 2. In a survey of employees, 7% of those asked were in favor of at least one of the 3 proposals made by the management, 50% of them were in favor of proposal A, 30% favored proposal B, and 20% favored proposal C. If 5% favored all three proposals, what percentage of those asked favored more than one of three proposals?
