Answer:
(a) The probability is 0.6514
(b) The probability is 0.7769
Step-by-step explanation:
If the number of accidents occur according to a poisson process, the probability that x accidents occurs on a given day is:
Where a is the mean number of accidents per day and t is the number of days.
So, for part (a), a is equal to 3/7 and t is equal to 1 day, because there is a rate of 3 accidents every 7 days.
Then, the probability that a given day has no accidents is calculated as:
On the other hand the probability that February has at least one accident with a personal injury is calculated as:
P(x≥1)=1 - P(0)
Where P(0) is calculated as:
Where a is equivalent to (3/7)(1/8) because that is the mean number of accidents with personal injury per day, and t is equal to 28 because 4 weeks has 28 days, so:
Finally, P(x≥1) is:
P(x≥1) = 1 - 0.2231 = 0.7769
Answer:
The amount invested in gold bullion by Mr. Eliot = $50,000
Step-by-step explanation:
Total amount of savings Me. Eliot ha s = $150,000
Let us assume the amount invested in gold bullion = $m
So, the amount invested in bank = $150,000 - m
Now, 5% on m =
So, the profit in gold bullion = 0.05 m
and 3% on (150,000 -m) =
= 4,500 - 0.03 m
So, the profit in bank = 4,500 - 0.03 m
Now, the total profit = $5,500
⇒Profit from gold bullion + ban = $5,500
⇒0.05 m + 4,500 - 0.03 m = $5,500
or, 0.02 m = 1000
⇒ m = 1000/0.02 = 50,000
Hence, the amount invested in gold bullion = m = $50,000
