Question #cd284 Algebra Linear Inequalities and Absolute Value Theoretical and Experimental Probability 1 Answer salamat Apr 6, 2017 a.#0.2816# b. #0.0563# Explanation: let say #p# = probability of contaiminated and #q# = probability of uncontaiminated. therefore, #p = 5/20 = 1/4# and #q = 15/20 = 3/4# # n = 10# Q.a . #P(X = 2) = "^10C_2(1/4)^2(3/4)^8 = 0.2816# Q.b. #P(X = 0) = "^10C_0(1/4)^0(3/4)^10 = 0.0563# Answer link Related questions How do you calculate experimental probability?
