B. You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.The probability of choosing two even numbers?

Answer 1

A.

First pick:
There are 7 tiles. Two tiles have numbers less than 7, the 6 and the 5.
p(number less than 7) = 2/7

Second pick:
Now there are 6 tiles left.
There are two multiples of the 4, the 8 and the 20.
p(multiple of 4) = 2/6 = 1/3

Overall probability:
p(less than 7 followed by multiple of 8) = 2/7 * 1/3 = 2/21

B.

First pick:
There are 7 tiles. Four tiles have even numbers.
p(even number) = 4/7

Second pick:
Now there are 6 tiles left.
There are three even numbers left.
p(even number) = 3/6 = 1/2

Overall probability:
p(even number followed by even number) = 4/7 * 1/2 = 4/14 = 2/7

Answer 2

The probability of the compound event is 2/7.

The probability of  a number less than 7 and then a multiple of 4 is 2/21

The probability of choosing two even numbers is 2/7.

We have given you randomly choose a tile. Without replacing the first tile, you choose a second tile.

We have to determine the probability of choosing a number less than 7 and then a multiple of 4.

What is the formula for probability?

$P(A)=\frac{Autcome in A}{Outcome in sample space}$

For a first pick

There are 7 tiles. Two tiles have numbers less than 7, the 6 and the 5.

p(number less than 7) = 2/7

Similarly for the second pick:

Now there are 6 tiles left.

There are two multiples of the 4, then 8, and the 20.

P(multiple of 4)

= 2/6

= 1/3

Overall probability:

p(less than 7 followed by multiple of 8)

= 2/7 * 1/3

= 2/21

For the first pick:

There are 7 tiles. Four tiles have even numbers.

p(even number) = 4/7

For the second pick:

Now there are 6 tiles left.

There are three even numbers left.

p(even number)

= 3/6

= 1/2

Therefore the overall probability is

P(even number followed by even number)

= 4/7 * 1/2

= 4/14

= 2/7

Therefore the probability of choosing two even numbers is 2/7.
