This is the same program as CuteDramiones, I just need help, like a nudge, then If I still don't get it, a bigger hint pls... Or if you don't want to talk, the whole solution.

P(< 15 from Box A)  = (14/20)  =   7/10      (1)

 

P(even or > 25 from Box B)   = 

 

P(even from Box B) + P(>25 from Box B)  - P(even and > 25 from Box B)  =

 

(10/20) + (5/20) - (3/20)  = 12/20  = 3/5     (2)

 

So.....the probability of  (1) and (2)   =   7/10  *  3/5  =    21 /  50

Hear is a answer from Cphill 

 

P(< 15 from Box A)  = (14/20)  =   7/10      (1)

 

P(even or > 25 from Box B)   = 

 

P(even from Box B) + P(>25 from Box B)  - P(even and > 25 from Box B)  =

 

(10/20) + (5/20) - (3/20)  = 12/20  = 3/5     (2)

 

So.....the probability of  (1) and (2)   =   7/10  *  3/5  =    21 /  50
