A recent survey of 1030 U. S. adults selected at random showed that 689 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.

66.89% probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

The number of adults who think that firefighters have very high prestige. So

Total outcomes:

The total number of adults surveyed, so

Probability:

66.89% probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
