Question

In a survey of 200 ladies, it was found that 142 like coffee, while 58 dislike it. Find the probability that a lady chosen at random (i) likes coffee, (ii) dislikes coffee. Select the correct answer from above options

Answer 1

It is given that Number of ladies = 200 Number of ladies who like coffee = 142 Number of ladies who dislike coffee = 58 Consider E1 as the event that the selected ladies like coffee So we get P (E1) = number of ladies who like coffee/ number of trials By substituting the values P (E1) = 142/ 200 We get P (E1) = 0.71 Consider E1 as the event that the selected ladies dislike coffee So we get P (E2) = number of ladies who dislike coffee/ number of trials By substituting the values P (E2) = 58/ 200 We get P (E2) = 0.29
