Answer:
<u>P(three tails) = 27/125 or 21.6%</u>
<u>P(two tails followed by one head) = 18/125 or 14.4%.</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the questions correctly:
Probability of getting a head when a biased coin is tossed = 2/5
therefore,
Probability of getting a tails when a biased coin is tossed = 3/5
2. Find the following probabilities and select the correct solution.
P(three tails) =
3/5 * 3/5 * 3/5 = 27/125 or 21.6%
P(two tails followed by one head) =
3/5 * 3/5 * 2/5 = 18/125 or 14.4%.
3/5 = .6 and 4/10 = .4, so 3/5 is greater than 4/10

Answer:
452.16 m³
Step-by-step explanation:
d = 3h = 3×4m = 12 m
r = d/2 = 12m/2 = 6 m
V = Ab×h = π·r²·h
= 3.14×36m²×4m
= 452.16 m³
