2)the probability of white and white, without replacement
3) the probability of blue and red, with replacement
4) the probability of white and red, without replacement

Answer 1

1) red and red with replacement = (2/5)*(2/5) = 0.16 = 16%
2) white and white without replacement = (2/5)*(1/4) = 0.1 = 10%
3) blue and red with replacement = (1/5)*(2/5) = 0.08 = 8%
4) white and red without replacement = (2/5)*(2/4) = 0.2 = 20%
