एक यादृच्छिक चर X मान 0,1,2,3 ग्रहण करता है | चर X का माध्य `1.3` है | यदि `P(x=3) = 2 P(X=1)` तथा `P(X=2) = 0.3` हो , तो `P(X= 0 )`है |

A random variable X takes the values 0, 1, 2, 3 and its mean is 1.3 . If P(X= 3) = 2P(X= 1) and P(X= 2) = 0.3 , then P(X= 0) is equal to

A random variate X takes the values 0, 1, 2, 3 and its mean is 1.3. If P(X= 3) = 2P(X= 1) and P(X= 2) = 0.3 , then P(X= 0) is equal to

A random variable X takes the values 0,1,2,3 and its mean = 1,3 .If P(X=3) =2P(X=1) and P(X=2) = 0.3 then P(X=0) is

If X is a Poisson variate with P(X=2)=(2)/(3)P(X=1) , find P(X=0) and P(X=3)

If X is a Poisson variate with P(X=2)=(2)/(3)P(X=1) , find P(X=0) and P(X=3)

A random variate X takes the values 0,1,2,3 and its mean is 1.3. If P(X=3)=2P(X=1) and P(X=2)=0.3, then P(X=0) is equal to

ABCD is a trapezium in which AB parallel to DC and its diagonals intersect at P. If AP = (3x - 1) cm, PC = (5x - 3) cm, BP = (2x + 1) cm and PD = (6x - 5) cm, then the length of DB is: ABCD एक समलम्ब है जिसमें AB, DC के समानांतर है तथा इसके विकर्ण P पर एक दूसरे को काठते हैं | यदि AP = (3x - 1) सेमी, PC = (5x - 3) सेमी, BP = (2x + 1) सेमी तथा PD = (6x - 5) सेमी है, तो DB की लंबाई क्या होगी ?
