Annotations

Step-by-step explanation:

Let A = research project will be well planned

B =  research project will be well executed

P(A) = 0.8

P(B) = 0.9

P(AB) = 0.72

a)  the probability a research project is well planned; or well executed; or well planned and well executed=

(b)  the probability a research project is only well planned or well executed but not well planned and well executed :

c)  the probabilit y a research project which is well planned will also be executed = P(AB) = 0.72

d)  the probability a research project which is well executed will also be well planned = 0.72

e)  the probability a research project is not planned and/or not well executed

f)  the probability a research project is only well planned

g)  the probability a research project is only well executed=P(B) = 0.9

h ) Are these two events (Well Planned / Well Executed) Mutually Exclusive?

No, since P(AB) is not 0

i ) Are these two events (Well Planned / Well Executed) Independent

Yes, since P(AB) = P(A) P(B)
