The probability of getting a total that is a factor of 21 is 0.22
<u>Explanation:</u>
Factor of 21 is = 1, 3, 7, 21
Out of all the factors of 21, we cannot get 21 when the two die are rolled as the maximum sum that can be obtained is 12
The possible combinations are:
(1,2) (1,6)
(2,1) (2,5)
(3,4)
(4,3)
(5,2)
(6,1)
Total outcome = 6 X 6
= 36
Number of outcomes that is the factor of 21 is 8
The probability of getting a total that is a factor of 21 is 
p(21) = 0.22
Therefore, the probability of getting a total that is a factor of 21 is 0.22
Answer:
28.56/linear yard
32.2256/linear meter
121.77984k
Step-by-step explanation:
a) Scale = k9.52*3 = 28.56/linear yard
b) Scale = k9.52*3.28 = 32.2256/linear meter
c) Cost = 3.9 * 32.2256 = 121.77984k
