You roll a standard number cube once find p(7)

P (7) = 0

Step-by-step explanation:

We are given that a standard number cube is rolled once and we are to find the probability of getting the number 7.

We know that a standard number cube has numbers ranging from 1 to 6. So there is no side on the cube with the number 7.

Therefore, the probability of getting a 7 by rolling the cube once is zero.

P (7) = 0

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
