Answer: [tex]\frac{5}{138}[/tex]
Step-by-step explanation:
Given
Amber has 24 marbles
7 are red, 5 are blue,
[tex]\Rightarrow[/tex]24-12=12 is green
[tex]\text{Probability}=\text{chosing a blue marble out of 24 }\times \text{Chosing another blue out of 23}\\P=\frac{5}{24}\times \frac{4}{23}=\frac{5}{138}[/tex]
Amber has 24 marbles. 7 are red, 5 are blue. The probability that they are both blue = 5/ 138.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Amber has 24 marbles. 7 are red, 5 are blue.
The number of green marbles
24 - 12 = 12 is green
The probability that they are both blue
= choosing of blue marbles from 24 x choosing of blue marbles from 23
= 5/ 24 x 4/ 23
= 5/ 138
