Answer:

B 2/6

Step-by-step explanation:

2 of the 6 possible outcomes are ones that are of interest. A "fair" die means the mutually-exclusive outcomes have equal probability, so ...

P(4 or 5) = P(4) +P(5) = 1/6 + 1/6 = 2/6

Divide 650 sweets between Cia, Mia and Tia in the proportion 3:4:6. Calculate how many sweets each girl gets.

vodka [1.7K]

Answer:

150, 200, 300

Step-by-step explanation:

sum the parts of the ratio , 3 + 4 + 6 = 13 parts

divide the total by 13 to find the value of one part of the ratio

650 ÷ 13 = 50 ← value of 1 part of the ratio , then

3 parts = 3 × 50 = 150 ← number of sweets Cia gets

4 parts = 4 × 50 = 200 ← number of sweets Mia gets

6 parts = 6 × 50 = 300 ← number of sweets Tia gets

Assume that the Poisson distribution applies and that the mean number of aircraft accidents is 9 per month. Find P(0), the prob

Ugo [173]

Answer: 0.0001

It is unlikely to have a month with no aircraft accidents .

Step-by-step explanation:

Given : Mean number of aircraft accidents = 9 per month

The Poisson distribution formula :-

$\dfrac{e^{-\lambda}\lambda^x}{x!}$ , where $\lambda$ is the mean of the distribution.

If X = the number of aircraft accidents per month, then the probability that in a month, there will be no aircraft accidents will be :-

$\dfrac{e^{-9}(9)^0}{0!}=0.000123409804087\approx0.0001$

Hence, the probability that in a month, there will be no aircraft accidents = 0.0001

Since this is less than 0.5 , therefor it is unlikely to have a month with no aircraft accidents .
