    The value of k and P(X<3) are equal to

    Maths-General

    1. k equals fraction numerator 1 over denominator 10 end fraction comma P left parenthesis X less than 3 right parenthesis equals fraction numerator 3 over denominator 5 end fraction    
    2. k equals fraction numerator 1 over denominator 10 end fraction comma P left parenthesis X less than 3 right parenthesis equals fraction numerator 3 over denominator 10 end fraction    
    3. k equals fraction numerator 3 over denominator 10 end fraction comma P left parenthesis X less than 3 right parenthesis equals fraction numerator 1 over denominator 10 end fraction    
    4. k equals fraction numerator 1 over denominator 24 end fraction comma P left parenthesis X less than 3 right parenthesis equals fraction numerator 5 over denominator 12 end fraction    

      Answer:The correct answer is: k equals fraction numerator 1 over denominator 10 end fraction comma P left parenthesis X less than 3 right parenthesis equals fraction numerator 3 over denominator 10 end fraction
