Firs movie was 100min
Second movie was 1h and 55min
1h is 60min
So 60+55=115
Ans:second movie was longer by 15min
Probability of winning a grand prize is 1/10
Probability of winning a basic prize is 11/20
What is the probability of two independent events?
If A and B are two independent events, then P(A and B) = P(A) * P(B).
If Events A and B are independent, the probability that either Event A or Event B occurs is: P(A or B) = P(A) + P(B) - P(A and B).
Solution:
P(A) = no. of A / total possibility
= 4/10
P(B) = no. of 1's/total possibility
= 3/12
= 1/4
Now,
To win a grand prize you need an "A" and "1" .
∴ P(A and B) = P(A) × P(B)
= 4/10 × 1/4
P(A and B) = 1/10
Now ,
To win a basic prize you need to spin an "A" or a "1"
∴ P(A or B) = P(A) + P(B) - P(A and B)
= 4/10 + 1/4 - 1/10
= 3/10 + 1/4
∴ P(A or B)= 11/20

Answer:
x = 8.39
y = 55.2
Step-by-step explanation:
9² + 1² - 2(9)(1)cos(50) = x²
x = 8.39
9/sin(y) = x/sin(50)
sin(y) = 0.8215200692
y = 55.23724927
