Sir, In 2nd last question, how can it be sure that two blue pens were drawn in first attempt only? Can't there be possibility of drawing 1 blue pen & 1 black pen in first attempt and then 1 blue pen in the 2nd attempt? I think the statement of this question needs to be precise. please reply.

sir mera ans to 3/7 aa rha hai or mera hi nahi bahoot students ka yahi ans aa rha hai so please sir clear this doubt....

@mohitpathak5472 7 лет назад

Yeah...even i have the same doubt!!! Yaha par permutation vala concept bhi lgna chahiye as different orders are possible. Aur agar ham same chiz last question me kre to answer 1/7 ki jagah 3/7 ban jayega as there will be 3 different ways in which 2 chocobars and 1 ice-cream can be withdrawn. So 1/7+1/7+1/7 = 3/7. But ye clear nhi hai ki yaha different order consider karne hai ya nhi????

@starlight2384 7 лет назад

answer is 1/7 4/8 * 3/7 * 4/6 = 1/7 OR (4c2/8c2 ) * (4c1/6c1)= 1/7

@kushagrayadav5468 5 лет назад

the question at 39:20 is not complete as per the solution suggests. In solution it seems that question should have said in first attempt when 2 were drawn both the pens must have been blue and in the last attempt the pen must be black. But reading question it seems that you have to get 2 blue and 1 black no matter in what order they come, means -- 2 blue together + 1 black = 2 blue & 1 black 1 blue, 1 black + 1 blue = 2 blue & 1 black In this way answer would be different.

1. A box of bolts contains 8 thick bolts, 5 medium bolts and 3 thin bolts. A box of nuts contains 6 that fit the thick bolts, 4 that fit the medium bolts, and 2 that fit the thin bolts. One bolt and one nut are chosen at random. What is the probability that nut fits the bolt ? 2. A batch of 100 capacitors contains 73 which are within the required tolerance values, 17 which are below the required tolerance values and the remainder are above the required tolerance values. Find the probabilities that when randomly selecting a capacitor and then a second capacitor : i. both are within the required tolerance values when selecting with replacement, and ii. the first one drawn is below and the second one drawn is above the required tolerance value, when selection is without replacement. 3. Fifteen telephones have just been received at an authorized service center. Five of these telephones are cellular, five are cordless and the other five are corded phones. Suppose that these components are randomly allocated the numbers 1, 2, 3, ………., 15 to establish the order in which they will be serviced. i. what is the probability that all the cordless phones are among the first ten to be serviced ? ii. what is the probability that after servicing ten of these phones, phones of only two of the three types remain to be serviced ? iii. What is the probability that two phones of each type are among the first six serviced ? 4. Veroboard pins are packed in packets of 20 by a machine. In a thousand packets, 40 have less than 20 pins. Find the probability that if 2 packets are chosen at random, one will contain less than 20 pins and other will contain more than 20 pins. 5. The probability of a component failing in one year due to excessive temperature is 20 1 , due to excessive vibration is 25 1 and due to excessive humidity is 50 1 . Determine the probabilities that during a one year period a component : i. fails due to excessive temperature and excessive vibration, ii. fails due to excessive vibration or excessive humidity, and iii. will not fail because of both excessive temperature and excessive humidity.
