Here's the answer to  the second one, LF :  https://web2.0calc.com/questions/please-help-asap_22

 

First one

P(A)  = 5/8       P(B)  =  3/4    P (A  ∩ B)  =  15/32 

 

D is the true statement because

 

P(A  ∩ B)  = P(A) P(B)

15/32   =  (5/8) (3/4)

15/32  = 15/32

 

Last  one

 

Prob of a boy chosen at random does not wear glasses  =  33/45  = 11/15  = 73%

 

 

 

cool cool cool
