Step-by-step explanation:
I understand that it means that out of every 10 hours, a cat spends 7 sleeping (not 7 hours in a day).
this means that a cat is sleeping

a percentage stays constant, this means that a cat sleeps 70 % of each 10 hours, but also 70% of the day.
Jamie can only buy 5 tickets priced at $30 total because if he buys one more he is no longer spending less than $36
Answer:
P(A and B) is greater than 1 is never happened ⇒ C
Step-by-step explanation:
Two events are independent if the result of the second event is not affected by the result of the first event
If A and B are independent events, the probability of both events is the product of the probabilities of the both events P (A and B) = P(A) · P(B)
∵ The probability of any event is less than 1
∵ P(A) < 1
∵ P(A) > 
- That means P(A) is greater than half and less than 1
∴
< P(A) < 1
∵ P(B) < 1
∵ P(B) > 
- That means P(B) is greater than half and less than 1
∴
< P(B) < 1
∵ P(A and B) = P(A) . P(B)
- Remember the product of any fractions less than 1 is less than 1
∴
< P(A) . P(B) < 1
- That means any expression equals to P(A) . P(B) must be greater
than
and less than 1
∴
< P(A and B) < 1
∴ P(A and B) is greater than 1 is never happened
