The probability of getting a head when a biased coin is tossed is 2/5. the coin is tossed three times. find the following probabilities and select the correct solution. p(three tails) = . p(two tails followed by one head) = .

P(three tails) = 27/125 or 21.6%

P(two tails followed by one head) = 18/125 or 14.4%.

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%.

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12
