Answer:
Option B is correct
Step-by-step explanation:
Here, h be the number of hours.
As per the statement:
The temperature is 50 degrees Fahrenheit.
⇒Initial temperature = 50 degrees Fahrenheit
It is also given that:
The temperature will decrease by 4 degrees F each hour.
1 hour temperature will be = -4 degree F
then;
In h hour temperature = -4h degrees F
We have to find the the temperature be below 32 degrees F.
Total Temperature be below 32 degrees F means:
where, h represents the number of hours.
Therefore, the the temperature below 32 degrees F will be
Answer:
Step-by-step explanation:
Given a basket, the probability of a ball to end there is (because there are m baskets).
Then, the probability of a ball to end in other basket is .
Finally, the probability of the basket to remain empty after n throws is
This last is because, given n independets events with probability p, the probability for all of them to happen is . In this case
