Question

There are 10 flashcards with digits from 0 to 9 written on them. Andrew drew the card with 2 on it. He is about to draw another card. What is the probability that he will be able to write a two-digit multiple of 4 using these two cards?

Answer 1

• 8/9

Explanation:

Two-digit multiples of 4 with one digit being 2 are:

• 12, 20, 24, 28, 32, 52, 72, 92

So there are 7 possible options out of 9

• p = 8/9
