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.

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.

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

2 in 7.

A touch judge runs along the touch[side] line observing play. It is up to him to see when the ball is in touch and where the ball goes into touch for line outs. The touche judge may also see off the ball incidents the main ref does not notice and can help in decision making.
