Question

A box contains 88 green marbles and 18 white marbles. If the first marble chosen was a green marble, what is the probability of choosing, without replacement, a white marble?

Answer 1

Answer: $\dfrac{6}{35}$

Step-by-step explanation:

Given : Number of green marbles in the box =88

Number of white marbles in the box = 18

Total marbles : 88+18=106

If the first marbles is already chosen was a green, then the number of white marbles remains same but the total marbles will be 105

Now, the probability of choosing, without replacement, a white marble :-

$\dfrac{18}{105}=\dfrac{6}{35}$

The probability of choosing, without replacement, a white marble =$\dfrac{6}{35}$
