1. michael has 8 coins in his pocket, and 3 of these are loonies. he reaches into his pocket and pulls out a coin at random. determine the odds against the coin being a loonie. (1 mark)
Answer
# Explanation:
## Step1: Find number of non - loonies
There are 8 coins in total and 3 are loonies. So the number of non - loonies is $8 - 3=5$.
## Step2: Calculate odds against
The odds against an event is the ratio of the number of unfavorable outcomes to the number of favorable outcomes. Here, the number of unfavorable outcomes (coin is a loonie) is 3 and the number of favorable outcomes (coin is not a loonie) is 5. So the odds against the coin being a loonie is $5:3$.
# Answer:
$5:3$
