What percentage of the star's surveyed show evidence of planets?

(a) About 50%
(b) Less than 5%
(c) About 30%
(d) Less than 1%

My estimate using wobble, dimming and shifting came out to be 40%, but the answer does not have it. Any suggestions?

To determine the percentage of stars that show evidence of planets, we will consider the given options:

(a) About 50%: This option suggests that approximately half of the surveyed stars have evidence of planets.

(b) Less than 5%: This option implies that less than 5% of the surveyed stars exhibit evidence of planets.

(c) About 30%: This choice proposes that around 30% of the surveyed stars show signs of planets.

(d) Less than 1%: This option indicates that less than 1% of the surveyed stars demonstrate evidence of planets.

Based on the given options, the most appropriate answer would be (c) About 30% as it falls within a reasonable range of probability for the percentage of stars with evidence of planets.

To determine the percentage of stars surveyed that show evidence of planets, we need to gather relevant data. This question implies that there is a study or survey that has been conducted to determine this percentage.

To find the answer, we should look for scientific studies or data from reputable sources that have conducted surveys of stars and identified exoplanets. One of the most well-known surveys that has identified exoplanets is the Kepler space telescope mission conducted by NASA.

A simple internet search using keywords such as "percentage of stars with exoplanets" or "Kepler mission results" would provide us with the necessary information.

It should be noted that the exact percentage may vary depending on the specific survey, as well as the criteria used to identify and classify exoplanets. However, based on current scientific knowledge, option (c) "About 30%" is generally considered a reasonable estimate for the percentage of stars surveyed that show evidence of planets.
