Question

A bag has 4 red marbles,5 blue, 3 green and 1 yellow. what is the probability of pulling a red marble.

Answer 1

Answer:

4/13 is the answer

total = 4+3+5+1= 13

let a be the event of getting red marbles= total is 4

probability=4/13

Answer 2

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
