im thinking 25% or 4% or 40%

OpenStudy (anonymous):

or 2.5 or 0.4

OpenStudy (welshfella):

not sure about this one i think you are given that he is blond so that is the base for the probability so i think its 14%

OpenStudy (welshfella):

there is no list of options?

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

its fill in the blank

OpenStudy (welshfella):

i would put 14% there though i'm not absolutely sure

OpenStudy (anonymous):

ok thanks

OpenStudy (welshfella):

the other possibility is 0.35 * 0.14 = 0.049

OpenStudy (welshfella):
