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%.
It probably is 2 1/4 because 1/2 to the second power is 1/4 then added to 2 will be 2 1/4. Hope this helps! Good Luck with your homework!!!
6.32 is the final answer! :)
2abc - 3ab ║ 2 (2) (3) (4) - 3 (2) (3)
You would multiply and the products - you are going to subtract
2 × 2 × 3 × 4 = 48
3 × 2 × 3 = - 18

answer: 30
Answer:
Step-by-step explanation:
- 1/a + 1/b =
- b / ab + a / ab =
- (b + a) / ab
The common denominator is ab
Correct choice is D
