Answer :
The probability of the Toronto Argonauts not winning the Grey Cup is 0.80 or 80% when rounded to two decimal places, given that the odds against them winning are 1:4.
The student asked about the probability that the Toronto Argonauts do not win the Grey Cup, given that the odds against them winning are 1:4. The odds 1:4 mean there's one chance for winning to four chances of losing. To find the probability of an event that is not winning, we can calculate it using the odds against the team.
First, we'll convert the odds to a probability. The total number of outcomes is the sum of the odds, which is 1 (for winning) + 4 (for losing) = 5 total outcomes. Now, the probability of not winning (losing) is the number of outcomes for losing divided by the total number of outcomes, which is 4/5.
Rounded to two decimal places, the probability of the Toronto Argonauts not winning the Grey Cup is 0.80 or 80%.
