Answer:

The probability of tails coming up is $\dfrac{3}{5}$

D is correct

Step-by-step explanation:

Suppose a coin has been altered so that the probability of heads coming up is 2/5.

A coin has two possibility either head or coin.

We are given probability of heads coming up is 2/5

$P(H)=\dfrac{2}{5}$

The sum of probability of all value is 1.

$P(H)+P(T)=1$

$\dfrac{2}{5}+P(T)=1$

$P(T)=1-\dfrac{2}{5}$

$P(T)=\dfrac{3}{5}$

Hence, The probability of tails coming up is $\dfrac{3}{5}$

Find the Range and Domain of the Binary relations

sukhopar [10]

Answer:

A = {3,5,6}

B = {1,3}

<u><em>A x B</em></u> = {(3,1),(3,3),(5,1),(5,3),(6,1),(6,3)}

Domain of A x B = (The x figures in ascending order)

=> {3,5,6} (Figures repeating more than once must be written only 1 time)

Range of A x B = (The y figures in ascending order)

=> {1,3}

<u><em>B x A </em></u>= {(1,3),(3,3),(1,5),(3,5),(1,6),(3,6)}

Domain of B x A = {1,3}

Range of A x B = {3,5,6}

Hello,

$u_{1} =4\\
 u_{2} =4*q\\
 u_{3} =4*q^2\\
...\\

 u_{9} =4*q^8\\\\
==\textgreater\ 4*q^8=1024\\
==\textgreater\ q^8=256\\
==\textgreater\ q=2\mbox{( and there is a problem in the question) } \ or \ q=-2\\
if\ q=2 \ then\ \sum_{i=0}^{8}\ 4*(2)^i= 4*\dfrac{1-2^9}{1-2} =2044\\

if \ q=-2 \ then\ \sum_{i=0}^{8}\ 4*(-2)^i= 4*\dfrac{1-(-2)^9}{1+2} =684\\
