Abasket contains 6 pieces of paper numbered from 1 to 6. a hat contains the letters a, b, and c. if a blindfolded person picks a number and a letter, what is the probability that the number is even and the letter is a?

The two events are independent, so the probability of both happening is the product of the two.

Probability of picking an even number is 3/6=1/2
Probability of picking the letter A is 1/3 = 1/3

Product of probability of two independent events = (1/2)(1./3)=1/6.
