For events A and B, suppose P(A) = 0.7 and P(A and B) = 0.28. Are A and B independent?

Yes

Step-by-step explanation:

Since P(A)=0.7 and P(A and B)=0.28, then P(B) must be 0.4 because 0.7*0.4=0.28.

Since P(A and B) is a combined probability, P(A) and P(B) are independent.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!
