Question

A recent survey of 1070 U.S. adults selected at random showed that 669 consider the occupation of firefighter to have very great prestige. Estimate the probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige. (Enter a number.)

Answer 1

Answer:

≅0.63

Step-by-step explanation:

Number of US adults selected for the survey= 1070

number of adults who considered the job of fire fighter to have great prestige= 669

Probability= Favorable number of outcome/ total number of outcomes

therefore, the probability that a U.S. adult selected at random has very great prestige = $\frac{669}{1070}$

= 0.6252≅0.63

Answer 2

Answer: The probability that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige is 0.63.

Step-by-step explanation:

As per given ,

The number of U.S. adults surveyed = 1070

The number of U.S. adults U.S. adults that they consider the occupation of firefighter to have very great prestige. = 669

Now , The probability that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige :

$=\dfrac{\text{Number of U.S. adults consider the occupation of firefighter to have very great prestige}}{\text{Total US adults surveyed}}\\\\=\dfrac{669}{1070}\\\\=0.62523364486\approx0.63$

Hence, the probability that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige is 0.63.
