Given the statement:
A jar contains 6 red and 8 blue marbles. A marble is drawn from the jar.
Determine the probability that a red marble is drawn.
Solution:
In order to determine the probability that the red marble is drawn, we simply need to add the total number of marbles first.
= 6 + 8
= 14
Divide the total number of red marbles by the total number of marbles.
= 6/14
=0.4285
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.4285)(100)
= 42.85%
FInal answer:
The probability of drawing a red marble is 42.85%
