The Black Lives Matter (BLM) movement began on July 13, 2013. The main focus of BLM for years has been on bringing awareness to police brutality against the African American community and to people of color (Hispanics and Blacks). There have been many movements in the past addressing racial injustice against the Black community (Civil Rights movements from 1965 to 1969 and the 1992 Los Angeles Riots). Do you believe this current movement will bring about any change? If so,...

Additional question: It is known that 1/3 of the St. Catharines adult population does not accumulate enough physical activity to experience health benefits. Lack of physical activity is a risk factor for various health conditions including cardiovascular disease, cerebrovascular disease, and osteoporosis. If 10 adults are randomly selected from this population: a) What is the probability that exactly 8 of them will not be physically active? b) What is the probability that at least 9 will not be physically active?...
