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:
375< y < 525
Step-by-step explanation:
The minimum is 15* 25 = 375
the maximum is 15 * 35 =525
He can earn any amount between these two values
6.4 months Because 10% of $1,100 is $110
multiply 110 by 6.4 and you get 704
so 6.4 months
72 percent.
Divide 576 into 800 to get 72%
