Total no. of possible outcomes = 25 {1, 2, 3, … 25} E ⟶ event of getting a prime no. No. of favourable outcomes = 9 {2, 3, 5, 7, 11, 13, 17, 19, 23} Probability, P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"` =9/25 (`barE`) ⟶ 𝑒𝑣𝑒𝑛𝑡 𝑜𝑓 𝑛𝑜𝑡 𝑔𝑒𝑡𝑡𝑖𝑛𝑔 𝑎 𝑝𝑟𝑖𝑚𝑒 𝑛𝑜. 𝑃(`barE` ) = 1 − 𝑃(𝐸) = 1 − 9/25 =16/25 Text Solution Solution : Total set ={1,2,3,4,...,25}=25 This determines size of set<br> Prime numbers is it ={2,3,5,7,11,13,17,19,23}<br> size =9<br> Probability =9/25 Text Solution Solution : A = {2, 3, 5, 7, 11, 13, 17, 19, 23} <br> `P(A) = (9)/(25)` Open in App Suggest Corrections 0 No worries!
