P(Being a Male or being Nursing Major) = P(Being male) + P(Being Nursing Major) - P(Being Male and Being nursing Major)
P(Being male) = Number of Male students / Total number of students = 1111/3432
P(Being Nursing Major) = Number of Nursing Major students / Total number of students = 698/3432
P(Being Male and Being nursing Major) = Number of Nursing Major and Male students / Total number of students = 98/3432
P(Being a Male or being Nursing Major) = P(Being male) + P(Being Nursing Major) - P(Being Male and Being nursing Major) = 1111/3432 + 698/3432 - 98/3432 = 1711/3432
P(Being a Female or not being Nursing Major) = P(Being female) + P(Not Being Nursing Major) - P(Being Female and Not Being nursing Major)
P(Being female) = Number of female students / Total number of students = 2321/3432
P(Not Being Nursing Major) = Number of Not Nursing Major students / Total number of students = 2734/3432
P(Being Female and Not Being nursing Major) = Number of Not Nursing Major and Female students / Total number of students = 1721/3432
P(Being a Female or not being Nursing Major) = P(Being female) + P(Not Being Nursing Major) - P(Being female and Not Being nursing Major) = 2321/3432 + 2734/3432 - 1721/3432 = 3334/3432
P(Not Being a Female or being Nursing Major) = P(Not Being female) + P(Being Nursing Major) - P(Not Being Female and Being nursing Major)
P(Not Being female) = Number of Not being female students / Total number of students = 1111/3432
P(Being Nursing Major) = Number of Nursing Major students / Total number of students = 698/3432
P(Not Being Female and Being nursing Major) = Number of Nursing Major and Not Female students / Total number of students = 98/3432
P(Being Not Female or being Nursing Major) = P(Being Not female) + P(Being Nursing Major) - P(Not Being female and Being nursing Major) = 1111/3432 + 698/3432 - 98/3432 = 1711/3432
