Answer 1

the 27 came from adding the amount of coins
7+8+3+9=27

Answer 2

In the question, it is given that, Zayne has a bag filled with coins. the bag contains 7 quarters, 8 dimes, 3 nickels, and 9 pennies.. he randomly chooses a coin from the bag.

Probability of selecting quarter is

`(7)/(27)`

And probability of selecting nickel is

`(3)/(27)`

So to find the probability of selecting quarter or a nickel is the sum of the two probabilities, that is

`(7)/(27)+ (3)/(27) = (10)/(27)`
