1) A bag contains 6 yellow counters, 3 green counters and 2 red counters. What is the probability that the first counter taken is red? (someone already helped with this but there’s more) 2) If the first counter chosen is red, what is the probability that the second counter taken out is also red?

3) If the first counter chosen is green and the second counter chosen is yellow, what is the probability that the third counter is yellow?

4) The probability of choosing yellow as the first choice is 6/11 with the given number of counters in the bag. How many counters might you add so that the probability of choosing green is 6/11?
