given,

number of red marbles = 4

number of blue marbles = 5

number of green marbles = 3

number of yellow marbles = 1

total number of marbles = 4 + 5 + 3+1 = 13

Probability of pulling a red marble is ,

P (red marble ) = number of red marbles/total number of marbles

P(red) = 4/13

Hence ,

As a fraction the probability is 4/13

As a decimal , the probability is 4/13 = 0.307

And as a percent , probability = 4/3 x 100 = 30.7
