Question

a bag contains 4 distinct white and 2 distinct red balls. Two balls are drawn from the bag. Find the probability that both balls are white

Answer 1

Hey buddy here is your answer.

total number of white balls-4

total number of red balls-2

total number of balls-6 (4+2)

Probability of white ball-4/6=2/3.

Thank you.

Answer 2

The probability that both balls are white is 2/5

Solution:

Given that,

White balls = 4

red balls = 2

Total number of balls = 6

The probability of an event is:

$Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}$

Find the probability that both balls are white

Consider balls are drawn one by one without replacement

Then,

$Probability = \frac{4}{6} \times \frac{3}{5} = \frac{12}{30} = \frac{2}{5}$

Thus the probability is found
