Use the identity P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
P(A)=0.50
P(B)=0.60
P(A ∪ B) = 0.30
=>
P(A ∪ B) = P(A)+P(B)-P(A ∩ B)
=(0.50+0.60)-0.30
=0.80
Answer:
257 is the answer
Step-by-step explanation:
If you take and divide 8.23 and 3.19 u come out with a big number but the first three are all that matter. then you need to subtract 8-5 and u get 2.579937 but since your exponent is only 10^3 you get 257.9937, but you can get rid of the numbers after 257.
