GRE?

@shoebmoin10 5 лет назад

46:13 the answer is 1/5 and not 1/36 since it is already given that the sum of the faces of dices is 8 we should not consider all 36 possibilities

@akhileshkhadseofficial 5 лет назад

I too had the same query

@himanshuupadhayay7843 5 лет назад

no u r wrong bro...total outcomes will be 36.

@lalitkumarjha2066 4 года назад

Yeah, you are right.It should be 1/5

@akhil338 4 года назад

Solution :-A dice has 6 faces So there are 6 possible outcomes Dice is rolled once and then again So total possibilities = 6 × 6 = 36 The sum should be 8 of the 2 throws So which combination of numbers from 1 to 6 will yield us a sum of 8 They are - (2, 6); (6, 2); (3, 5); (5, 3); (4, 4); So there are total 5 possibilities where addition is 8. But only 1 possibility where first throw of dice is 4. So, Probability for first throw to be 4 and sum to be 8 = 1/36.

@gokulsivakumar4930 4 года назад

@sawandeepgavel54 2 года назад

Q 10).......Answer would be 1/5 instead of 1/36 coz the sample space would shrink due to the given condition

@techcryptotalks7656 Год назад

Even i think so. cause if given the 6 probability in total in first throw of dice then it also includes 1. And if 1 is considered then the sum can never be 8. And it is like( considering previous questions of shirts, 6 black, 4 red , 2 white and 3 blue), if the question says, black shirt is never picked so what is the probability of choosing blue shirt? so here probability would be 3/9. Because question already sates that black shirt is never picked so no of total probability decreases. Likewise, in this question, the sum is 8, so it automatically eradicates the possibility of coming 1 is removed. So left total possibility is 5 in total. So answer is 1/5. Again, if it asked in both the throw the probability of coming 4 and 4 for summing up 8 then it would be only (1/5) * (1/5) = 1/25 . Hope it helps. My own calculation, verify it first. P.S= Great content sir. Keep it up @CareeRride. And if my explanation is correct then please do or atleast pin my comment. Thanks!!

@manaskhandekar4137 3 года назад

For the 15th sum, I just did P = (G,G) OR (B,G) for two consecutive positions... P = [ (5/7) × (4/6) ] + [ (2/7) × (5/6) ] P = 5/7

@justlaugh4860 3 года назад

@asishranjansahoo3537 3 года назад

No it cant be considered here as the statement for the second box is given after it says it replaces one of the tshirts to another (so here another box means the second box).

@asishranjansahoo3537 3 года назад

it would have been as you saying only when both info regarding the boxes would have been given in the first two statements followed by the replacement statement.

Question number 10 should be 1/5 because among the possible outcomes of sum of 8, we have to choose 1 condition. Any output should have sum of 8.

@MuhammadBilal-wg3mz Год назад

Yes, me too think so. Because, since the event of having the sum being ‘8’ already happened, we are left with only five possibilities; among which only 1 out of 5 yields 4 in first throw.

@@lks5343 I don't think so. They are just possibilities that add up to 8. yet the real sample space is still 36

@raghurajpratap5015 3 года назад

nooooo..total number of possibilities were still 6×6. so the answer would be 1/36.

in question 8 we can use (4c2*3c1)/15c3 . it will be more time saving.

@hemantprasad1018 6 лет назад

Thank you so much for this tutorial. By the way I've doubt in question no.10 in this video. so, far I've understood from your lecture the total outcomes will be 5 and not 36. Becasue we're concerned with the outcomes not only giving 4 but also the sum must be 8. So that is 1/5 instead of 1/36.

@osprangers 6 месяцев назад

On question 10, I feel it is more natural to read it as a conditional probability question, i.e. P(first throw was 4 | sum of two throws is 8), which I'd think is 1/5 (5 possibilities to have sum equal to 8, out of which 1 has 4 as first throw). The author now answers the question 'what is the probability of throwing two 4s when rolling a dice twice', ignoring the information we have about the sum.
