Question

What is the probability that each student will win gift cards that are at least 25$

Answer 1

We need to find the probability that a student will winn a gift card of at leat $25.

We use probability formula:

$Probability=\frac{\text{Favorable events}}{total\text{ events}}$

In this case, the total number of events is: 8

this is because we have 8 possible triangles as the result.

The favorable events are the number of triangle that have a value of at least $25, which are the following:

The only two favorable events are $25 and $50, so

Favorable events = 2

Substituting this into our probability formula:

$Probability=\frac{\text{Favorable events}}{total\text{ events}}=\frac{2}{8}$

We can simplify this probability as 1/4, or as 0.25

Answer: 2/8=1/4=0.25
