Homework Statement
From 52 cards we draw one .Whats the probability that the drawn card is divisible by 4
Now : in my notebook its 12/52=3/13 .But shouldn't it be 13/52 ? BECAUSE clearly if we multiply 13 *4=52
Same problem : Whats the probability that of 52 cards I draw one that is divisible
with 10 or 11 .In notebook its like this P(a)+p(b)= 4/52+4/52=8/52=4/26=2/13
BUT shouldn't this as well be 5/52+5/52
