Answer:
75%
Step-by-step explanation:
Probability of a day being sunny (P(S)) = 0.9
Probability of driving when sunny (P(Ds)) = 1-0.75 = 0.25
Probability of a day NOT being sunny (P(N) = 1- 0.9 = 0.1
Probability of driving when sunny (P(Dn)) = 1-0.25 = 0.75
The probability of a day being sunny given that the person is driving (S) is defined as the ratio between the probability of the person driving and the day being sunny by the probability of the person driving:

There is a 75% probability that it's a sunny day.
Answer:
Y = 40
Step-by-step explanation:
44 - 66y + 65y + 5 = 9
49 - y = 9
-y = -40
y = 40
Answer:
cos60 - cos 72
Step-by-step explanation:
you can have an angle measure between 60 and 72 hence cos 60 - cos 72
