Question

Find the probability. What is the probability that a card drawn from a deck of 52 cards is not a 10?

a) 12/13
b) 1/13
c) 1/10
d) 9/10

Answer 1

So, for the first one, with replacement, the probability of drawing a 10 first is given by 4/52 = 1/13. Since we replace it, the probability of drawing a heart on the second attempt is 13/52 = 1/4. So, the probability of drawing a 10 and then heart with replacement is 1/4 * 1/13 = 1/52.
