Let X represent the number of pictures you post until one is "liked." (X represents the photo number that is actually liked.) Find:
μXμX:
(rounded to 3 decimals)
σXσX:
(rounded to 3 decimals)
P(X=5)P(X=5):
(rounded to 4 decimals)
P(X<9)P(X<9):
(rounded to 4 decimals)
P(X>11)P(X>11):
(rounded to 4 decimals)
P(8≤X≤13)P(8≤X≤13):
(rounded to 4 decimals)
