Idk if people haven't answered because i didn't show work or not but there isn't much work to show in the first place here's what i tried anyway.
a. probability its even .5 (5/10)/ probability its greater than 40(1/5) .2 = 2.5 which is over one so obviously wrong
b. probability its greater...
A number is selected randomly from a container containing all the integers from 10 to 50 find
a) p(even|greater than 40)
b) p(greater than 40| even)
c) p(prime| between 20 and 40)
please provide an explanation, thanks a lot =D
