At North High School, the probability of randomly selecting a student who is in band is 0.42 and the probability of randomly selecting a student who is involved in ROTC is 0.38. If these two events are independent, what is the probability of randomly selecting a student who participates in both band and ROTC?

If you could answer these your a life saver

M? aoc=96 ? space, m, angle, a, o, c, equals, 96, degree \qquad m \angle boc = 8x - 67^\circm? boc=8x? 67 ? space, m, angle, b, o, c, equals, 8, x, minus, 67, degree \qquad m \angle aob = 9x - 75^\circm? aob=9x? 75 ? space, m, angle, a, o, b, equals, 9, x, minus, 75, degree find m\angle bocm? bocm, angle, b, o, c:

Does 9q + 7 also equal 7 + 9q ? (simplifying algebraic expressions)
