ment?; What is the probability of drawing a second red ball given that the first ball drawn was red?; What is the probability of getting a red ball randomly?
P(2 red balls without replacement) = P(1st red ball) x P(2nd red ball | 1st red ball is red), where P is probability.
The probability of getting 2 red balls with replacement is the probability of drawing a red ball multiplied by the probability of drawing a second red ball. This can be written as P(2 red balls with replacement) = P(1st red ball) x P(2nd red ball).
The probability of drawing a second red ball given that the first ball drawn was red is the probability of drawing a red ball given that the first ball drawn was red. This can be written as P(2nd red ball | 1st red ball is red) = P(2nd red ball | 1st red ball is red).
The probability of getting a red ball randomly is simply the probability of drawing a red ball. This can be written as P(Random red ball) = P(Red ball).
