3/4
Write the proportion formula like this: P(event) For this problem you would write it like this: P(pick red) Since there are 4 blocks (two red and two blue) there is a 1/2 chance that you would pull out a red block.
Hope this helps!

Answer:
the lowest passing score would be x = 298
Step-by-step explanation:
School wishes that only 2.5 percent of students taking test pass
We are given
mean= 200,
standard deviation = 50
We need to find x
The area under the curve can be found by:
2.5 % = 0.025
So, 1- 0.025 = 0.975
We need to find the value of z for which the answer is 0.975
Looking at the z-score table, the value of z is: 1.96
Now, using the formula:
z = x - mean/standard deviation
1.96 = x - 200/50
=> 1.96 * 50 = x-200
98 = x - 200
=> x = 200+98
x = 298
So, the lowest passing score would be x = 298

The probability of not landing on blue is 2/3rds.
Supplementary and adjacent.
Two angles are called supplementary when their measures add up to 180 degrees.
Adjacent angles are two angles that have a common vertex and a common side but do not overlap.
