Question

A box contains 9 green marbles and 17 white marbles. If the first marble chosen was a white marble, what is the probability of choosing, without replacement, another white marble? Express your answer as a fraction or a decimal number rounded to four decimal places.

Answer 1

Answer:

16/25

Step-by-step explanation:

Given

Number  of green marbles = 9

Number of White marbles = 17

Total number of marbles = 26

Probability of picking a white marble = 17/26

When a white marble is picked without replacement,

Probability of picking another white marble after first picking a white marble

= 16/25

= 0.64

This is because the total number of marbles would have reduced from 26 to 25 and the number of white marbles from 17 to 16.
