The Captain has probability \dfrac{1}{2} 2 1 ​ start fraction, 1, divided by, 2, end fraction of hitting the pirate ship. The pi

rate only has one good eye, so he hits the Captain's ship with probability \dfrac{1}{6} 6 1 ​ start fraction, 1, divided by, 6, end fraction. If both fire their cannons at the same time, what is the probability that both the pirate and the Captain hit each other's ships?

Answer:

0.083 is the required probability.

Step-by-step explanation:

We are given the following in the question:

Probability of captain hitting pirate's ship =

P(A) = \dfrac{1}{2}

Probability of pirate hitting the captain's ship =

P(B) = \dfrac{1}{6}

Probability that both the pirate and the Captain hit each other's ships:

P(A\cap B) = P(A)\times P(B)

Putting values, we get,

P(A\cap B) =\dfrac{1}{2}\times \dfrac{1}{6} = \dfrac{1}{12} \\\\P(A\cap B) = 0 .083

0.083 is the probability that both the pirate and the Captain hit each other's ships.

Karen wants to advertise how many chocolate chips are in each big chip cookie at her bakery. she randomly selects a sample of 69
Tomtit [17]

Answer: (10.1989,\ 11.0011)

Step-by-step explanation:

Given : Sample size : n=69

Sample mean : \overline{x}=10.6

Standard deviation : s=1.7

Significance level : \alpha:1-0.95=0.05

Then , Critical value : z_{\alpha/2}=1.96

The formula to confidence interval is given by : -

\overline{x}\pm z_{\alpha/2}\dfrac{s}{\sqrt{n}}\\\\\Rightarrow\ 10.6\pm (1.96)\dfrac{1.7}{\sqrt{69}}\\\\\approx10.6\pm0.4011=(10.6-0.4011,10.6+0.4011)=(10.1989,\ 11.0011)

Hence, the 95% confidence interval for the number of chocolate chips per cookie for big chip cookies= (10.1989,\ 11.0011)

Amit’s school bus travelsat 36km/hr and Sushma’s school bus travels at 11 m/s. Whose school bus is faster ?
UNO [17]

Answer:

This answer is not originally mine so Don give me credit

Step-by-step explanation:

Amit's school bus in m/s will be

36×1000/3600

36 × 10/36

= 10 m/s

While sushma's school bus has speed of 11 m/s

so sushma's school bus is faster than Amit's school bus
