Need asap pls a. 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 a number less than 7 and then a multiple of 4 is? 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?

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

Here’s the answer. you’re supposed to use 2900 times the interest rate and then add your original amount of money. now you get 2997.15
