Question
You have a bag with 100 blocks inside of it. If 31 blocks are red, 49 blocks are blue, and 20 blocks are black, what is the probability (in decimal form) of pulling a blue cube from the bag?

To find the probability of pulling a blue block from the bag, we can use the formula for probability:
\[
P(\text{event}) = \frac{\text{number of favorable outcomes}}{\text{total number of outcomes}}
\]
In this case, the event is pulling a blue block. We know from the problem statement:
- The total number of blocks is 100.
- The number of blue blocks is 49.
Now we can substitute these values into the probability formula:
\[
P(\text{blue}) = \frac{49}{100}
\]
Calculating the probability in decimal form:
\[
P(\text{blue}) = 0.49
\]
Thus, the probability of pulling a blue block from the bag is \( \boxed{0.49} \).
\[
P(\text{event}) = \frac{\text{number of favorable outcomes}}{\text{total number of outcomes}}
\]
In this case, the event is pulling a blue block. We know from the problem statement:
- The total number of blocks is 100.
- The number of blue blocks is 49.
Now we can substitute these values into the probability formula:
\[
P(\text{blue}) = \frac{49}{100}
\]
Calculating the probability in decimal form:
\[
P(\text{blue}) = 0.49
\]
Thus, the probability of pulling a blue block from the bag is \( \boxed{0.49} \).
