Kim has a strong first serve; whenever it is good (that is, in) she wins the point 70% of the time. Whenever her second serve is

mestny [16]

Lets put ti this way:
P[1st serve good & wins point] = 60% * 70% = 42% = A
P[2nd serve good & wins point] = 40% * 76% *57% = 17.328% = B 

1. P[win point] = A+B = C = 59.328% <------- 
2. P[1st serve good | win point ] = A/C = 42 / 59.328 = 0.707 or 70.7%
Please remember that 2nd serve come into use only if 1st serve is not good

Answer:

<h2>Option C : 25</h2>

Step-by-step explanation:

Given, 

Number of rainy days = 18

Number of cloudy days = 14

Number of sunny days = 29

Therefore, 

Number of days either sunny or cloudy = 14 + 29 = 43

So,

Number of more days sunny or cloudy than rainy are

= 43 - 18 = 25

Hence,

Option C 25 is the correct answer.
