She is not correct. All integers are rational numbers.
The sum of the angles of the shaded area is 120°, and there are 360° in a circle, so the probability of landing on it is 1/3 of 33.33% repeating
Answer:
b. 0.45.
Step-by-step explanation:
The total possible outcome of a probability is 1
Given;
Probability that both lights will be red when she reaches them = 0.22
Probability that the first light will be red and the second light will not be red = 0.33
Probability that the second light will be red when she reaches it = x
These are all the possible outcomes, therefore
0.22 + 0.33 + x = 1
0.55 + x = 1
x = 1 - 0.55
x = 0.45
Option b
Answer:
x=25/6
Step-by-step explanation:
3x+11=9x-14
11=6x-14
25=6x
x=25/6
