Answer:

Prob = (3 / 11) * (6 / 10) = 18 / 110 = 9 / 55

Step-by-step

The probability that the first is red equals 3/11 (favourable outcomes divided by possible outcomes). Under condition that this occurs the probability that the second is blue equals 6/10. The probability of the described event is then the product of these factors. This according to the rule P(A and B)=P(A)*P(B|A).

here you go sis!
