Question

Seth had a bag with 4 green 5 yellow and 6 blue marbles if Seth draws a yellow marble and does not replace it what is the probability that the second marbles he draws is yellow

Answer 1

`(2)/(7)`

Explanation:

Total Number of green Marbles=4 marbles

Total Number of Yellow Marbles=5 marbles

Total Number of Blue Marbles=6 marbles

Total number of marbles= 15 marbles

Seth draws a yellow marble and does not replace it , Number of balls left= 14 marbles

Probability of drawing a Yellow ball=
`(Number of yellow balls)/(Number of balls left)`

Probability of drawing a Yellow ball=
`(4)/(14\\)`

Probability of drawing a Yellow ball=
`(2)/(7)`

Hence the correct answer is
`(2)/(7)`
