Hey there! Welcome to Brainly!
Let's see how many marbles we have in total.
12+11+17+5=45
We want to find the probability of selecting a marble that is not blue. Let's see how many marbles aren't blue.
12+11+5=28
We have this probability out of 48.
28/48
We simplify, giving us 7/12 or about 58.33%.
I hope this helps!
Answer: [tex]\dfrac{28}{45}[/tex]
Step-by-step explanation:
Given : The total number of marbles = [tex]12+11+17+5=45[/tex]
The number of blue marbles = 17
Then, the number of marbles except blue = [tex]45-17=28[/tex]
Then, the probability that you will not choose a blue marble is given by :-
[tex]\text{P(not blue)}=\dfrac{\text{Number of marbles not blue}}{\text{Total marbles}}\\\\=\dfrac{28}{45}[/tex]
Hence, the probability that you will not choose a blue marble = [tex]\dfrac{28}{45}[/tex]
