of each event.
a. Rolling a number less than 9
b.rolling a multiple of 3
c.rollinh a number grrater than 6
The probability of rolling a number less than 9 is P ( A ) = 2/3
The probability of rolling a multiple of 3 is P ( B ) = 1/3
The probability of rolling a number greater than 6 is P ( A ) = 1/2
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
a)
Rolling a number less than 9
There are 8 numbers less than 9 on the dodecahedron (1, 2, 3, 4, 5, 6, 7, and 8), out of a total of 12 numbers. So the probability of rolling a number less than 9 is:
P(rolling a number less than 9) = 8/12 = 2/3
The likelihood of rolling a number less than 9 is relatively high, as 2 out of every 3 rolls will result in a number less than 9.
Therefore , the probability is P ( A ) = 2/3
b)
Rolling a multiple of 3
There are 4 multiples of 3 on the dodecahedron (3, 6, 9, and 12), out of a total of 12 numbers. So the probability of rolling a multiple of 3 is:
P(rolling a multiple of 3) = 4/12 = 1/3
The likelihood of rolling a multiple of 3 is moderate, as only 1 out of every 3 rolls will result in a multiple of 3.
Therefore , the probability is P ( B ) = 1/3
c)
Rolling a number greater than 6
There are 6 numbers greater than 6 on the dodecahedron (7, 8, 9, 10, 11, and 12), out of a total of 12 numbers. So the probability of rolling a number greater than 6 is:
P(rolling a number greater than 6) = 6/12 = 1/2
The likelihood of rolling a number greater than 6 is relatively high, as 1 out of every 2 rolls will result in a number greater than 6.
Therefore , the probability is P ( C ) = 1/2
Hence , the probability is solved

Answer:
a = 8/12 (2/3)
b = 4/12 (1/3)
c = 6/12 (1/2)
Step-by-step explanation:
a= 1-8 = 8 numbers less than 9
b= 3,6,9,12 = 4 numbers multiple of 3
c = 7-12 = 6 numbers higher than 7
1. a=c
2.
3. b-a=c-b
4. a
5. if a=b, then b=c
I think #2 is correct ,but I don't know about the others
Options 2 and 5 i.e., and are the correct statements such that .
Ratio is the mathematical indication that tells how many times one number contains another.
Reciprocate the given proportion both sides-
So, option 2 is correct.
Now, if then, the proportion will become-
So, option 5 is correct.
Thus, options 2 and 5 are the correct statements.

Setting up a proportional relationship between mirror and lamppost, the height of the lamppost is 10 feets.
Setting up a proportional relationship :
Cross multiply :
Hl × 3 = 6 × 5
3Hl = 30
Hl = (30 ÷ 3)
Hl = 10
Therefore, the height of the lamppost is 10 feets.

Answer: 10 feet
Step-by-step explanation:
Let h be the height of lamppost.
Since both the person and the lamppost are standing vertical to the ground, making similar right triangles.
Because the two triangles are similar, the ratio of their sides is the same.
Therefore, we have
Hence, the height of the lamppost = 10 feet.
