Answer:
![\boxed{\sf 6 u + \dfrac{10}{3}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%206%20u%20%2B%20%5Cdfrac%7B10%7D%7B3%7D%7D)
Explanation:
Given expression:
![\sf \rightarrow \dfrac{2}{3} (5+9u)](https://tex.z-dn.net/?f=%5Csf%20%5Crightarrow%20%5Cdfrac%7B2%7D%7B3%7D%20%285%2B9u%29)
distribute inside parenthesis
![\sf \rightarrow \dfrac{2}{3} (5)+ \dfrac{2}{3} (9u)](https://tex.z-dn.net/?f=%5Csf%20%5Crightarrow%20%5Cdfrac%7B2%7D%7B3%7D%20%285%29%2B%20%5Cdfrac%7B2%7D%7B3%7D%20%289u%29)
multiply variables
![\sf \rightarrow \dfrac{10}{3} + \dfrac{18}{3} u](https://tex.z-dn.net/?f=%5Csf%20%5Crightarrow%20%5Cdfrac%7B10%7D%7B3%7D%20%2B%20%5Cdfrac%7B18%7D%7B3%7D%20u)
simplify following
![\sf \rightarrow 6 u + \dfrac{10}{3}](https://tex.z-dn.net/?f=%5Csf%20%5Crightarrow%20%206%20u%20%2B%20%5Cdfrac%7B10%7D%7B3%7D)
19.2 is between integers 19 and 20 :)
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:
2/5
