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%.
Answer:
the answer is C
Step-by-step explanation:
there isn't much to learn here this is just something that you come to know off the top of your head
Area=Length x Width (A=LW)
A=30.5 x 12.5
A=381.25
it should be 100/3 or 33.3 repeating
Answer:
4(2x + 3)
Step-by-step explanation:
Given
8x + 12 ← factor out the common factor of 4 from both terms
= 4(2x + 3)
