In analyzing hits by certain bombs in a war, an area was partitioned into 553 regions, each with an area of 0.95 km2. A total

Leto [7]

Answer:

Probability of having two hits in the same region = 0.178

mu: average number of hits per region

x: number of hits

e: mathematical constant approximately equal to 2.71828.

Step-by-step explanation:

We can describe the probability of k events with the Poisson distribution, expressed as:

$P(x=k)=\frac{\mu^ke^{-\mu}}{k!}$

Being μ the expected rate of events.

If 535 bombs hit 553 regions, the expected rate of bombs per region (the events for this question) is:

$\mu=\frac{\#bombs}{\#regions} =\frac{535}{553}= 0.9674$

For a region to being hit by two bombs, it has a probability of:

$P(x=2)=\frac{\mu^2e^{-\mu}}{2!}=\frac{0.9674^2e^{-0.9674}}{2!}=\frac{0.9359*0.38}{2}=0.178$

There are 24 men and 36 women in a choir.

Molodets [167]

Answer:

Step-by-step explanation:

Total members in the choir = 24 + 36 = 60

a) Percentage of men = $\frac{24}{60}*100$

= 4 * 10 = 40%

b) Percentage of women = 60%

c) Number of men =24 + 10 = 34 men

Number of women = 36 + 10 = 46

Total = 34 + 46 = 80

Percentage of men = $\frac{34}{80}*100= 42.5$ %

Percentage of women = (100 - 42.5)% = 57.5%
