Question A bag has 4 red marbles,5 blue, 3 green and 1 yellow. what is the probability of pulling a red marble. Answer as a fraction, decimal and percent

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 Log in to Reply

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 Log in to Reply

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
