Answer:
0.516
Explanation:
Given;
0 = sales fall
1 = sales are steady
2 = sales rise moderately
3 = sales rise a lot
Output generated : 0 1 0 2 2 0 0 1 2 3 2 0 2 0 2 2 1 2 3 1 2 2 2 0 3 0 0 2 1 2 1
Total number of outputs = 31
probability that sales will rise at least moderately
= P(sales rise moderately) + P(sales rise a lot)
= P(2) + P(3)
now,
The number of times 2 appeared in the output = 13
The number of times 3 appeared in the output = 3
probability that sales will rise at least moderately = [tex]\frac{13}{31}+\frac{3}{31}[/tex]
= [tex]\frac{16}{31}[/tex]
= 0.516
