Please mark me the brainlest

Step-by-step explanation:

Total number of adults in group = 20

Total number of women in group = 7

Total number of men in group = 13

Number of women who wear glasses = 4

Number of men who wear glasses = 2

P{someone who wear glasses} = Total number of persons who wear                 glasses / Total persons in the group

                                                     = 6/20

                                                     = 3/10
