Question

I need HELP!!!
You pick a card at random. Without putting the first card back, you pick a second card at random.
Cards- 6 7 8 9
What is the probability of picking an even number and then picking an even number? in percentage?

Answer 1

So you have 4 cards

and you pick up a card and you don't return it

Answer 2

how many of those cards are even numbers?

Remember, even numbers are 2, 4, 6, 8, 0
Odd numbers are 1, 3, 5, 7, 9

The four cards that you have are
6, 7, 8, 9

what's the probability of getting an even card the first time?

and then after that, you've removed an even card so you're left with only one even card out of three cards
so what is the probability of getting an even card now?

and then multiply the two probabilities
