Question

P(A)=.5

P(B)=.47
P(A l B)=.44
dependent

P(A ∩ B)=?
P(A ∪ B)=?
P(B l A)=?

Answer 1

P(A ∩ B)= 235

P(A ∪ B)= -183

P(B l A) = 47

Explanation:

solution:

here;

P(A)=.5

P(B)=.47

P(A l B)=.44

P(A ∩ B)=?

P(A ∪ B)=?

P(B l A)=?

now,

i) P(A ∩ B) = P(A)×P(B)

=5×47

=235

ii) P(A ∪ B) = P(A)+P(B)-P(A ∩ B)

=5+47-235

= -183

iii) P(B l A = P(A ∩ B) / P(A)

= 235/5

=47

Hello there , not sure about my answer if its correct but i tried so please let me know if its wrong ..:-)

Answer 2

mmmmmmmm okay but i can

try

p={AnB}=( )

p=(AuB)=(457)

p=(BIA)= mmmm
