A survey of 300 girls of a school was conducted and it was found that 108 girls like tea and 192 dislike it. Out of these girls one girl is selected at random. What is the probability that the selected girl (i) likes tea (ii) does not like tea.

Text Solution

Verified by Experts

Total number of girls = 300
Number of girls who like tea = 108
Number of girls who dislike tea = 192
(i) Let `E_(1)` = event that the selected girl likes tea, then
`P(E_(1))=(108)/(300)=(9)/(25)`
(ii) Let `P(E_(2))` = event that the selected girl does not like does not like tea, then
`P(E_(2))=(192)/(300)=(16)/(25)`
