Answer:0.12
Step-by-step explanation:
Using it's concept, it is found that there is a 0.45 = 45% experimental probability of the coin landing on tails.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, 9 out of 20 trials resulted in tails, hence the experimental probability is given by:
p = 9/20 = 0.45 = 45%.

Answer:
3. 273
4. 168
5. 189.25
Step-by-step explanation:
3. Triangle= .5 x 17 x 6 = 21
Rectangle= 18 x 14 = 252
252 + 21 = 273
4. Big rectangle (shaded)= 11 x18= 198
Small rectangle (right)= 5x4=20
Smaller rectangle (left)= 2x5=10
BR - (SR+SMR)
198-30=168
5. radius=5
Area of the circle= 25(pi)
Semi-circle= 39.25(not exact)
Rectangle= 10 x15=150
Rectangle + Semi-circle
150+39.25=189.25
