Question

A box contains five cards lettered A, A, B, C, D. If one card is selected at random from the box and NOT replaced, what is the probability that Jack will draw a “D” and then an “A”?

Answer 1

There is a 1/10 chance you draw an A and then D 10% chance

Explanation:

Probablitiy of drawing a D is 1/5, If the card is not replaced, then there are only 4 cards left. Probability of drawing an A is 2/4 (1/2)

1/5 x 2/4

1 x 2 = 2 2/2 = 1

5 x 4= 20 20/2 = 10
