First pick: 13/(13+19+8)=13/40
the second pick: 12/39
both: 13/40 *12/39=156/1560=0.1

A computer program contains one error. In order to find the error, we split the program into 6 blocks and test two of them, sele

There are $\dbinom62$ ways of selecting two of the six blocks at random. The probability that one of them contains an error is

$\dfrac{\dbinom11\dbinom51}{\dbinom62}=\dfrac5{15}=\dfrac13$

So $X$ has probability mass function

$f_X(x)=\begin{cases}\dfrac13&\text{for }x=1\\\\\dfrac23&\text{for }x=0\end{cases}$

These are the only two cases since there is only one error known to exist in the code; any two blocks of code chosen at random must either contain the error or not.

The expected value of finding an error is then

$\displaystyle\sum_{x=0}^1xf_X(x)=0\times\dfrac23+1\times\dfrac13=\dfrac13$

If a/b = c/d, then ad = bc.

Nikolay [14]

Answer:

The statement is true

see the explanation

Step-by-step explanation:

we have the proportion

$\frac{a}{b}=\frac{c}{d}$

we know that

To solve the proportion multiply in cross

so

$(a)(d)=(b)(c)$

$ad=bc$

therefore

The statement is true
