Afair 6-sided die is rolled four times. what is the probability that the sequence of rolls is 6,5,2,1? write your answer as a fraction or a decimal, rounded to four decimal places.

1/1296

Step-by-step explanation:

The probability of rolling any particular number is 1/6.  So the probability of rolling a particular sequence of four numbers is:

(1/6) (1/6) (1/6) (1/6)

1/1296

≈ 0.0008

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
