A survey on British Social Attitudes asked respondents if they had ever boycotted goods for ethical reasons (Statesman, January 28, 2008). The survey found that 23% of the respondents have boycotted goods for ethical reasons.

In a sample of six British citizens, what is the probability that two have ever boycotted goods for ethical reasons?

The probability that two have ever boycotted goods for ethical reasons.= .2789

Step-by-step explanation:

Given - The survey found that 23% of the respondents have boycotted goods for ethical reasons .

The probability of success ( p) = 23 = 0.23

The probability of failure ( q) = 1 - p = .77

n = 6  

Let X be the number of British citizens boycotted goods for ethical reasons.

The probability that two have ever boycotted goods for ethical reasons.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
