Step 1

In this problem, we have a bag with four red balls and six blue balls. We need to find the probability of picking a red ball at random.

Step 2

Let's start by listing our known values.

- Red Balls: 4

- Blue Balls: 6

Step 3

To find any probability, we first need the total number of possible outcomes. That's the total number of balls in the bag.

$$Total = 4 + 6$$

$$Total = 10$$

Step 4

The probability of an event is defined as the number of favorable outcomes divided by the total number of outcomes.

P(\text{Event}) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Outcomes}}

Step 5

In our case, the favorable outcome is picking a red ball. There are four red balls.

P(\text{Red}) = \frac{4}{10}
