What is the probability of rolling an even number o

ankoles [38]

Answer:

30%

Step-by-step explanation:

if it is six sides and the number only goes from one to six then you have to count how many even numbers are in between 1 and 6. That would be 2, 4, and 6. that is 3 numbers. And 3 over 10 is 3/10 which changes from a fraction into a percent and the percent is 30%. I hope you understand this sorry if you can't. Love ya bye.

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

Aleksandr-060686 [28]

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

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

Of the 150 students in 6th grade, 10% earned straight As last quarter. How many students earned straight As?

Dominik [7]

Answer: 15 students

Step-by-step explanation:

From the question, we are informed that there are 150 students in 6th grade, and that 10% earned straight As last quarter.

The number of students that earned straight As will be:

= 10% × 150

= 10/100 × 150

= 0.1 × 150

= 15 students
