Using Rule of Addition:
<span>It states that : "The probability that Event A or Event B occurs is equal to the probability that Event A occurs plus the probability that Event B occurs minus the probability that both Events A and B occur."
</span><span>
P(A or B) = P(A) + P(B) - P(A and B)
</span> = 0.7 + 0.55 - 0.3
= 1.55

The presentation pages are called "slides".
Answer:
A=input("Enter Number of Marks:")
b=[]
sum=0
i=0
for i in range(0,int(A)):
b.append(input("Enter Marks"))
sum+=int(b[i])
percentage1= (sum/int(A))*100
if percentage1>=20:
print("Grade A")
elif percentage1<=30 & percentage1>=20:
print("Grade B")
else:
print("Grade C")
Explanation:
The above program is in Python. And we are using here a dynamic list. And we are storing A marks in it. And then we are finding its average, and finally assigning the Grade as mentioned.
