total cards = 16

total number of ways of choosing two cards randomly = 16C2 where nCr = n!/r!

number of ways of choosing blue card = 4C1

number of ways of choosing yellow card = 2C1

Probability = favorable outcomes / total outcomes

probability of choosing blue card and yellow card = 4C1 * 2C1 /16C1

= 1/15 = 0.066
