Question

You select 16 marbles from a bag. The results are as follows: 4 blue marbles, 2 green marbles, 4 red marbles, 5 white marbles, and 1 yellow marbles. find P (not blue)

Answer 1

Total marbles are 16

No. of blue marbles are 4

The probability of finding blue marble is

`(4)/(16)=(1)/(4)`

Thus the probability that the marble is not blue is

`P(\text{not blue)=}1-(1)/(4)=(3)/(4)`

The answer is 3/4
