P (D) = .42, P (E) = .27, and P (D ∩ E) = .15 P (D U E)
Paul [167]

We know that P(D\cap E)=P(D)P(E)=\boxed{0.1134}.

And P(D\cup E)=P(D)+P(E)-P(D\cap E)=\boxed{0.5766}.

Hope this helps.

HELP ITS MY LAST QUESTION WITH STEP BY STEP
maks197457 [2]

Answer:

71

Step-by-step explanation:

This is the answer because:

1) First, add Andy's score and Janet's score in order to know how much they got in total:

  • Janet's score: 119 + 96 + 145 = 360
  • Andy's score: 127 + 74 + 88 = 289

2) In order to find how much more Janet scored, jus subtract Andy's score from Janet's score:

  • 360 - 289 = 71

Therefore, the answer is 71.

Hope this helps! :)
