    Sir wo 16 no. Ka problem waha aap jo 1 me se minus karna tha. Method 2
    Waha aap ne 2C2+2C1.5C1/7C2 lena tha iski value 11/21 aayegi.
    And finally 1-11/21=10/21
    Problem solved by method 2

    Sir 16th wale question me method 1 me aap numerator me 2C2 liye he.. par wo 2C2 + (2C1 × 5C1) hoga kyun ki "no ball is blue " ka opposite meaning hoga > "either both are blue or "one is blue and other is red /green"
    So finally numerator me 1 + (2×5) hoga and denominator me 21 hoga = 11/21...
    1 se subtract karenge to 10/21 aayega...

    1 Blue ball must be taken into count when subtracting from 1.

    Q.16
    1-p(Both are blue) means Probability both are not blue which means 1 can be blue
    So 1-p(both blue) does not mean no ball is blue

  • @elonmusk3579
    @elonmusk3579 3 года назад +2

    Q. 16
    👉Conditions (1 blue & 1 other) or (both Blue)
    👉 So P= [ 1- { ( 2c1 * 5c1) + 2c2 ) } / 7c2 ]
    👉 1- { (10+1) /21} = 10/21

  • @harjinderkaur1972
    @harjinderkaur1972 3 года назад +1

    i got the solution for following problem
    Problem: an urn contains 2 red 3 green and 2 Blue Balls if two balls are drawn at random then find the probability that no ball is blue
    scenario: while solving we get 10/21 by first method and was getting different answer for second method
    i solve above problem, please find solution below:
    1 - 2c1*5c1 + 2c2 / 7c2
    ans: 10/21
