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
[45 - (6 + 3)] x 27
Answer:
36x27
Step-by-step explanation:
[45-(6+3)]x27
[45-9]x27
36x27
Answer:
a=(c+2b)/5
Step-by-step explanation:
Like terms in one side to subject a.
When exchanging sides make sure u do inverse operations. Therefore;
9a - 4a = c + 2b
5a = c + 2b
a = (c+2b)/5
