A jar contains 6 red marbles numbered 1 to 6 and 8 blue
marbles numbered 1 to 8. A marble is drawn at random from
the jar. Round your answer to four decimal places. Find the
probability that the
a. marble is red:
b. marble is odd-numbered:
C. marble is red or blue:

Expert Solution

Step 1

From the given information, a jar contains 6 red marbles numbered 1 to 6 and 8 blue marbles numbered 1 to 8.

That is, the total number of marbles is 6+8=14.

A marble is drawn at random from the jar.

The probability that the marble is red is,

$P (r e d m a r b l e) = \frac{6}{14} = 0.4286$
