Answer: 1/45
Step-by-step explanation:
From thw question, we are told that there are:
Yellow marbles =2
Pink marbles =3
Blue marbles = 5
Total marbles = 2+3+5 = 10
The probability of drawing the first yellow ball will be= 2/10
Since the ball is not replaced, that means there will be 9 balls left and 1 yellow ball left. Therefore, the probability of drawing the second yellow ball will be = 1/9
The probability of drawing two yellow balls if they're not replaced will now be:
= 2/10 × 1/9
= 2/90
= 1/45
Answer:
