Answer:
sum is less than 5 or greater than 8 sum less than 5 is P(g) + P(3) + P(4) = 10 + 30+50 = 90 1000 1000 sum greater than 8 is
Step-by-step explanation:
The probability that the sum is a prime number or is exactly divisible by 4 = 0.63.
The probability that the sum is an odd number or exactly divisible by 3 = 0.65.
What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.
[tex]Probability = \frac{Favorable\ outcomes}{Total\ outcomes}[/tex]
Given data:
Sum Frequency
2 10
3 30
4 50
5 70
6 110
7 150
8 170
9 140
10 120
11 80
12 70
P (sum is a prime number or is exactly divisible by 4) = [tex]\frac{630}{1000}[/tex] = 0.63
Favorable outcome = sum is 2, 3, 4, 5, 7, 8, 11, 12.
P(sum is an odd number or exactly divisible by 3) = [tex]\frac{650}{1000}[/tex] = 0.65
Favorable outcome = sum is 3, 5, 6, 7, 9, 11, 12
