Mean = sum of outcomes / Total number of outcomes
15 = 10 + 12 + 18 + 11 + p + 19 / 6
15 x 6 = 70 + p
90 = 70 + p
p = 90 - 70
p = 20
15 = 10 + 12 + 18 + 11 + p + 19 / 6
15 x 6 = 70 + p
90 = 70 + p
p = 90 - 70
p = 20

mean = sum of all observation/total no. of observation
15 = 10+12+18+11+p+19/6
15 = 70+p/6
15*6 = 70+p
90=70+p
p = 90-70= 20
15 = 10+12+18+11+p+19/6
15 = 70+p/6
15*6 = 70+p
90=70+p
p = 90-70= 20
