    _2_ ×_2_×_2_ = 8 because we have coin which is mainly 2 outcome that is head and tail and three times

    The answer to the last coin question is 8 as there are 3 tosses and coin has 2 face ie heads and tails.... so
    2^3=2×2×2=8

    The result can be either head and tail.
    Imp point -head and tail.
    Therefore total no of outcomes= 2×2×2=8

    Question 3) the answer is 8 because the work would be seen as completed once we have taken all 3 results together and not individually therefore each coin toss will have 2 results so at the end of the three coin toss the total no. Of results that could be created are 2*2*2=8

  • @khushkapoor5230
    @khushkapoor5230 5 років тому +9

    No. Of faces a coin has =2
    No. Of times a coin tossed=3
    So, total no of outcomes =2*2*2=8

  • @warrior1741

    2×2×2=8 because conjunction "and" is used if the conjunction is replaced by "or" then it will be 2+2+2=6

    • @sanskaragarwal9730

      It can't be or because coin have only 2 side once it has to get repeated so the correct answer is 8

    Sir most of them answered 8 it looks correct but if we use the formula where n=3 ,and r= 2 because 1 toss can have 2 possibilities .so it will be
    3P2 ,which is 3!/(3-2)!=3.Is it correct ?

    सिक्के को पहली बार उछालने पर 2 परिणाम ( यानी Head या Tail) आने की सम्भावना बनती है। इसी तरह दूसरी और तीसरी बार उछालने पर भी 2-2 परिणाम आने की संभावना बनती है। चूंकि इस प्रक्रिया में 'या'(or) conjunction Use हो रहा इसलिए इसमें Fundamental principles of counting का Addition Rule apply होगा, अतः Total Outcomes (2+2+2=) 6 होगा।
