Answer: 0.5
Step-by-step explanation:
Given
There are 3 blue and 1 yellow marble
The chance of picking two marble out of 3 is 
The total no of ways of picking 2 marbles out of 4 is 
Therefore, the probability of picking 2 blue marbles
I cannot see the entire problem, but based on what I can see, vertical angles are involved. Just know that vertical angles are always equal. An example would be that 1 and 3 are vertical.
Looking at the problem, the sum of angle 1 and angle 3 is 314. Since angle 1 and angle 3 are equal, angle 1 and angle 3 are both equal to 157. If the question is asking you to solve for angle 4 or 2, then you would use supplementary angles. 180-157 is 23, so the measure or angles 2 and 4 is 23. If the question if something other than what I mentioned, let me know and I will answer that, but I hope what I have helped!
Answer:

Answer:
Step-by-step explanation:
11/3 + (7 - 11/5)
LCM of 3 and 5 is 15 so we have
55/15 + (105/15 - 33/15)
= 160/15 - 33/15
= 127/15.
