Answer:
<h2><em><u>23</u></em><em><u> </u></em><em><u>days</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em>
No. of days taken by Jenny to read 7 books
= 8
<em><u>So</u></em><em><u>,</u></em>
No. of days taken by her to read 1 book

<em><u>Therefore</u></em><em><u>,</u></em>
No. of days taken by her to read 20 books

- <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

- <em>[</em><em>On</em><em> </em><em>dividing</em><em>]</em>
= 22.85.....
- <em>[</em><em>On</em><em> </em><em>approximating</em><em>]</em>
= 23 days (approx. )
<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Jenny</u></em><em><u> </u></em><em><u>will</u></em><em><u> </u></em><em><u>take</u></em><em><u> </u></em><em><u>23</u></em><em><u> </u></em><em><u>days</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>read</u></em><em><u> </u></em><em><u>20</u></em><em><u> </u></em><em><u>books</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

Answer and Step-by-step explanation:
Given that probability of you winning each game = 0.68
And probability of you winning next game = 0.81
Your friend's chance of winning/you losing would be = 1-0.68= 0.32
also his chance of winning next game = 0.73
To find probability that you would win the series given that you need to win two games to win the series
= probability that you win first game and second game+ probability that you win first game, lose second game and win third game + probability that you lose first game, win second game and win third game
= 0.68*0.81+0.68*0.32*0.68+0.32*0.68*0.81
=0.8750
Therefore probability that you would win the series = 0.8750
Note: here we found the probability of winning by adding(or) up the three possible combinations that would result in a win
