Question

A jar contains 54 marbles each of which is blue,green or white the probabilty of selecting a blue marble is 1/3 and the probability of selecting a green marble is 4/9.How many white marbles are in the jar

Answer 1

here is the answer of your question

Answer 2

Answer:

Step-by-step explanation:

Let S be the sample space

n(S)= 54

Let A be the event of selecting a blue marble

P(A)=1/3

1/3=n(A)/54

n(A)=18

Let B be the event that the marble drawn out is green

P(B)=4/9

4/9=n(B)/54

n(B)=24

n(A)+n(B)=18+24=42

No. of white marbles=54-42=12
