There are 35 marbles in a bag: 9 blue marbles, 8 green marbles, 4 red marbles, 8 white marbles, and 6 yellow marbles. Find p(red). Write the probability as a fraction in simplest form, a decimal, and a percent.
The probability of selecting a red marble can be calculated by dividing the number of red marbles by the total number of marbles.
P(red) = Number of red marbles / Total number of marbles
P(red) = 4 / 35
As a fraction in simplest form:
P(red) = 4/35
As a decimal:
P(red) = 0.114
As a percent:
P(red) = 11.4%
