Of 12 possible building sites for factories, 5 have buried toxic waste sites that no one told you about! If you choose 3 of the sites for initial building locations, what is the probability you will be lucky enough to avoid any toxic waste sites?

Explanation:

Probability refers to the chance of occurrence of some event.

Number of building sites for factories = 12

Number of toxic waste sites = 5

So, number of non-toxic waste sites = 12 - 5 = 7

We need to find the probability that the 3 sites chosen for initial building locations are non-toxic.

Solution:

Probability = number of non-toxic waste sites / Number of building sites for factories =

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
