Answer:
Step-by-step explanation:
Convert mixed fraction to improper fraction.
÷
=
÷ 
Now use K C F method
K - Keep the first fraction
C - Change the division operation to multiplication
F- Flip the second number

10 red
8 blue
2 green
Total number = 20
Probability that Gina takes a red pen = number of red pens divided by the total = 10/20 = 0.5 = 50%
If she repeats the event, the second time the probability is the same: 0.5 = 50%
Probability of two events = probability of the first one multiplied by the probability of the second = 0.5 x 0.5 =0.25 = 25%
Answer:
Probability = 0.25 = 25%
Answer:
182
Step-by-step explanation:
850-125=725
725/4=181.25
So you need at least 182 tickets sold.
No, because an equilateral triangle is also equiangular so all sides must be 60° (60+60+60=180) and an obtuse angle is more than 90° so the triangle would not be equilateral.
