Question

According
to an? airline, flights on a
certain route are on time

8585?%

of
the time. Suppose
1010

flights
are randomly selected and the number of on time flights is
recorded. Use technology to find the probabilities. Use the Tech
Help button for further assistance.88

flights
are on time.88

flights
are on time.88

flights
are on time.66

and
88

?flights, inclusive, are
on time. Answer #1

Ans:

Given that

n=10,p=0.85

P(x=r)=10C_{r}*0.85^{r}*(1-0.85)^{10-r}

a)Yes,it is binomial distribution,as only two outcomes possible(whether on time or not) and independent trials.

b)

P(x=8)=10C_{8}*0.85^{8}*0.15^{2}=**0.2759**

c)Use below table for calculations:

P(atleast 8)=P(x>=8)

=P(x=8)+P(x=9)+P(x=10)

=0.276+0.347+0.197

**=0.820**

d)P(x<8)=1-P(x>=8)=1-0.820=**0.180**

e)P(6<=x<=8)=P(x=6)+P(x=7)+P(x=8)

=0.040+0.130+0.276=**0.446**
