Answer:
Probability distribution of demand.
Let X be the random variable for weekly demands.
The probability that the demand will be at least two but no more than six is expressed as,
P
(
2
≤
X
≤
6
)
=
P
(
X
=
2
)
+
P
(
X
=
3
)
+
P
(
X
=
4
)
+
P
(
X
=
5
)
+
P
(
X
=
6
)
=
0.16
+
0.14
+
0.12
+
0.10
+
0.08
=
0.62
Therefore, the required probability is 0.62.
