A bag contains 3 red balls and 4 green balls randomly draw one ball then replace it and randomly draw a second what is the percentage?

Drawing one red ball out of a bag that contains 3 red balls and 4 green balls is 3 in 7. If we are to randomly select one ball out of the bag and replace it (I assume with the same ball) then there are still 3 red balls and 4 green balls. The odds are still 3 in 7. It doesn't matter how many times you draw. Every time you draw a ball you have a 3 in 7 chance of pulling out a red ball.


Draw one ball colored red from a bag Draw one ball colored blue from the same bag Are these two mutually exclusive?

No. Drawing a red ball and then a blue ball from a bag are not mutually exclusive events, because the first event changes the probability of the second event, unless you return the first ball to the bag before drawing the second ball.


If a box contains one red ball and one blue ball and two people touch one ball randomly with a one in two chance of picking either what is the chance of the blue ball being picked twice?

One in four. The possibilities are; Red Red Blue Red Red Blue Blue Blue That means the number of ways an event can occur is one, while the number of possible outcomes is four. The definition of probability is the number of ways the event can occur over the number of possible outcomes, hence 1/4
