Crystal spun the spinner 20 times. 1 was the outcome 4 times out of 20 spins, so the experimental probability would be 4/20 or 1/5. Same goes for all the other ones.
Answer:
Step-by-step explanation:
<h3>Given</h3>
- If (s -a) = 5cm, (s -b) = 10cm, (s -c) = 1cm
- s = ?
<h3>Solution</h3>
<u>Add up the 3 equations and solve for s:</u>
- s - a + s - b + s - c = 5 + 10 + 1
- 3s = 16 + a + b + c
- s = 1/3(a + b + c + 16)
