Question

A jar contains 2 red marbles numbered 1 to 2 and 8 blue marbles numbered 1 to 8. A marble is drawn at random from the jar. Find the probability of drawing a red marble. Round your answer to four decimal places.

Answer 1

The probability of drawing a red marble from the jar is approximately 0.2000.

Step-by-step explanation:

To find the probability of drawing a red marble from the jar, we need to consider the total number of marbles in the jar and the number of red marbles. There are 2 red marbles numbered 1 to 2 and 8 blue marbles numbered 1 to 8. The total number of marbles in the jar is 10 (2 red + 8 blue).

The probability of drawing a red marble can be calculated as:

Probability of drawing a red marble = Number of red marbles / Total number of marbles

Probability of drawing a red marble = 2 / 10 = 0.2

Rounding to four decimal places, the probability of drawing a red marble is approximately 0.2000.
