The probability of obtaining two blue marbles without replacement is equal to 0.15.
We are given that:
The number of yellow marbles = 3
Number of red marbles = 9
Number of Blue marbles = 8
Total marbles = 3 + 9 + 8
Total marbles = 20
Now, we have to calculate the probability of obtaining two blue marbles without replacement.
The probability will be:
P( obtaining two blue marbles without replacement ) = 8 / 20 × 7 / 19
P( obtaining two blue marbles without replacement ) = 56 / 380
P( obtaining two blue marbles without replacement ) = 0.15
Therefore, the probability of obtaining two blue marbles without replacement is equal to 0.15.

Answer:
The answer is 24
Step-by-step explanation:
Answer:
FGE = 180 - (14 + 78)°
= 88°
so angle GEC = 88°
4x + 88 = 180
4x = 180 - 88
4x = 92
x = 92/4
= 23
Step-by-step explanation:
Hello!
That one inch is divided into eight even sections.
Look at the distance between where the insect's length ends and the "1". That space in between is how long each section is. It takes eight of those to make up one inch. The insect's length take up seven of the eight sections - almost an inch. So, the length of the insect is 7/8 in.
As for 0.875, that's the decimal form of the fraction. It means the same thing.
