A random experiment consists of rolling a tetrahedral die numbered 1 to 4 followed by an octahedral die numbered 1 to 8 .the following events were defined:
A:the result from the first die is a divisor of the result from the second die.
B:the product of the result from the first die and that from the second is a multiple of 4.
C :the sum of the result from the dice is an even number.
A :< >
B :< >
C :< >

-------------------------------------------------------------
The information below is about two events A and B resulting from a random experiment.
p (A') = 50%
p( B') = 0.4
A U B = Ω
p (A' U B' ) = 0.9
a) determine :
1)\x05P(A) :
2)\x05P(B) :
3)\x05P(A U B):
4)\x05P(A∩B):
