A study conducted by the American Skincare Organization found that, 38% of beachgoers wear sunblock and 65% of beachgoers wear sunglasses. Additionally, they found that 39% of beachgoers wear sunglasses and do not wear sunblock.

a. Define the events.
b. Write down the given probabilities.
c. What is the probability that a beachgoer does not wear sunglasses

Events: 1. Wearing sunblock (and no glasses?)

            2. Wearing sunglasses (and sunblock?)

            3. Wearing sunglasses and no sunblock

Probabilities: 1. 19/50, or 38%

                      2. 13/20, or 65%

                      3. 39/100, or 39%

Probability of not wearing sunglasses: 19/50, or 38%

Problem with this question: the percentages add up to much over 100%. If I have worked out this question wrong, please comment and I will fix it.

Step-by-step explanation:

Events:

Events are the possibilities, and the three events listed are: wearing sunblock, wearing sunglasses, and wearing sunglasses and no sunblock.

Probabilities:

38/100 simplifies to 19/50 when both sides are divided by 2

65/100 simplifies to 13/20 when both sides are divided by 5

39/100 cannot be simplified

Probability:

Assuming that group one does not wear sunglasses (because it is not listed if they do or do not wear sunglasses), we have that 38% of people do not wear sunglasses.

In conclusion, we get that 19/50 people do not wear sunglasses.

step-by-step explanation:

step-by-step explanation: the declaration of the rights of man and of the citizen (french: déclaration des droits de l'homme et du citoyen de 1789), set by france's national constituent assembly in 1789, is a human civil rights document from the french revolution.[1]

the declaration was drafted by the abbé sieyès and the marquis de lafayette, in consultation with thomas jefferson.[2] influenced by the doctrine of "natural right", the rights of man are held to be universal: valid at all times and in every place, pertaining to human nature itself. it became the basis for a nation of free individuals protected equally by the law. it is included in the beginning of the constitutions of both the fourth french republic (1946) and fifth republic (1958) and is still current. inspired by the enlightenment philosophers, the declaration was a core statement of the values of the french revolution and had a major impact on the development of freedom and democracy in europe and worldwide.[3]

the 1789 declaration, together with the 1215 magna carta, the 1689 english bill of rights (1689), the 1776 united states declaration of independence, and the 1789 united states bill of rights, inspired in large part the 1948 united nations universal declaration of human rights
