Amanda [17]

Answer:

3) 0.72

Step-by-step explanation:

The probability that tomorrow the Fed will cut interest rates (P(F)) OR the DJIA will go up (P(D)), is the sum of each event's individual probability minus their joint probability (Fed cutting interest rates AND the DJIA will going up, P(FD))

$P(F+D) = P(F) +P(D) - P(FD)\\P(F+D) = 0.5 + 0.67 - (0.5*0.9)\\P(F+D) = 0.72$

The probability that tomorrow the Fed will cut interest rates or the DJIA will go up is 0.72.
