Question

There are two boxes, Box 1 and Box 2. Each box has 8 red balls, 5 green balls, and 7 blue balls. Sahil takes one ball from Box 1 and places it in Box 2. He then draws two balls from Box 2 simultaneously.

What is the probability of Sahil selecting a green ball from Box 1?

Answer 1

The probability of Sahil selecting a green ball from Box 1 is 1/4 or 25%, calculated by dividing the number of green balls (5) by the total number of balls (20).

Step-by-step explanation:

The student is asking about the probability of selecting a green ball from Box 1. Since Box 1 has 8 red balls, 5 green balls, and 7 blue balls, the total number of balls is 8 + 5 + 7 = 20. To find the probability of selecting a green ball from Box 1, we can use the formula for probability:

P(Event) = Number of favorable outcomes / Total number of outcomes

Applying this formula to our situation:

P(selecting a green ball) = Number of green balls / Total number of balls

P(selecting a green ball) = 5 / 20 = 1/4

Therefore, the probability of Sahil selecting a green ball from Box 1 is 1/4 or 25%.

Answer 2

The probability of Sahil selecting a green ball from Box 1 is 1/4.

Step-by-step explanation:

To find the probability of Sahil selecting a green ball from Box 1, we need to calculate the total number of balls in Box 1 and the number of green balls in Box 1. Then we divide the number of green balls by the total number of balls to get the probability.

Box 1 contains 8 red balls, 5 green balls, and 7 blue balls, so the total number of balls is 8 + 5 + 7 = 20.

The number of green balls in Box 1 is 5.

Therefore, the probability of Sahil selecting a green ball from Box 1 is 5/20 = 1/4.

The question revolves around the concept of probability. In Box 1, there are 8 red balls, 5 green balls, and 7 blue balls, making a total of 20 balls. To find the probability of selecting a green ball from Box 1, we use the formula for probability, which is the number of favorable outcomes divided by the total number of outcomes.

The probability of Sahil selecting a green ball from Box 1 is therefore 5 (the number of green balls) divided by 20 (the total number of balls in Box 1). So, the probability is 5/20 or 1/4 when simplified.
