Ten tiles numbered 1 through 10 are placed in a bag. you randomly choose one tile. without replacing the first tile, you randomly choose a second tile. find the probability of choosing the 4 and then an even number. write your answer as a fraction in simplest form. plz me i don't understand this!

There are 10 counters in the bag and you want the 4

As their is only one for the probability is
1/10

There are now 9 counters left in the bag.
You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)

There are only four even counters in the bag of nine counters so the probability is
4/9

As you want both of these to occur, you need to multiply them

1/10 x 4/9 = 49/90
