If two marbles are drawn at random, the probability that they are both blue is 1/4
The formula for calculating the probability is given as:
Probability = Expected outcome/Total outcome
Since we are to find a probability of picking 2 blue balls
Pr(2 blue balls) = 6/12 * 6/12
Pr(2 blue balls) = 1/2 * 1/2
Pr(2 blue balls) = 1/4
Hence if two marbles are drawn at random, the probability that they are both blue is 1/4

Answer:
x=4
Step-by-step explanation:
they are the same
what you do is take 4x+23 and make it equal to 10x-1
4x+23=10x-1
+1 +1
4x+24=10x
-4x -4x
24=6x
/6 /6
x=4
