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:
1/3
Step-by-step explanation:
3+2+1=6 (Adding all the fish together)
There is 2 Bulegill fish
so it would be 2/6
Or it being simplified, 1/3
Step 1. 3 7/12 2 =52 Reduce the numbers
step 2. 7/4 2 =52 Reduce the numbers
step 3. 7/2 =52 Covert the fraction to decimal
step 4. 3.5 =52 Check the equality
answer: 3.5 =52
but this answer isn't true
Hope this helps :)
