Answer:
10.10% probability that in a day, there are 13 births. It is not very likely that in a day there will be exactly 13 births, but also not unlikely(lower than 5%).
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
In a recent year, a hospital had 4224 births.
An year has 365 days, so
Probability that in a day, there are 13 births.
This is P(X = 13).
10.10% probability that in a day, there are 13 births. It is not very likely that in a day there will be exactly 13 births, but also not unlikely(lower than 5%).
His salad calls for 8 cups of salad to maintain the given ratio. So the ratio is 5/8 for the strawberries.
Let x be what he needs for 1 cup of fruit
5/8 = x / 1 Cross multiply
5 = 8x Divide by 8
x = 5/8 of a cup of strawberries or
x = 0.625 cups of strawberries.
Multiply the bill by 20% to find the amount of the tip then add them together:
32.50 x 0.20 = 6.50
Tip = $6.50
Total bill = 32.50 + 6.50 = $39.00
