Need more context. It says how much does Grayson need to score? Does this mean there’s a certain score Grayson needs to reach to win? Or is it just a random scenario for a pattern question?
Answer:
Therefore, the mean and the standard deviation for the number of electrical outages (respectively) are 0.26 and 0.5765 respectively.
Step-by-step explanation:
Given the probability distribution table below:

(a)Mean
Expected Value, 
=(0*0.8)+(1*0.15)+(2*0.04)+(3*0.01)
=0+0.15+0.08+0.03
Mean=0.26
(b)Standard Deviation

Standard Deviation 

Therefore, the mean and the standard deviation for the number of electrical outages (respectively) are 0.26 and 0.5765 respectively.
Answer:
A. The Number of Lost games = 154 Games
B. Number of games won is greater than the number of games lost.
Step-by-step explanation:
A. how many games did they lose in both years?
Total Number of games = 104 tournaments x 3 Games in each tournament
Total Number of games = 312 Games
The No. of Lost games= Total Games in 2 years - Games won in 1st year - Games won in 2nd year
The No. of Lost games = 312 - 55 - 103
The No. of Lost games = 154 Games
B. Is the number of games won greater than the number of games lost?
Total Number of Games won = 158 Games
Total Number of Games lost = 154 Games
Hence, Total Number of Games won is greater than the Total Number of Games lost.
F(x<40)= 0.39+(x*0.24) This formula will quantify what you have written out above.
