Question

1. A contractor applies for two contracts:

Answer 1

Answer:

0.76

Step-by-step explanation:

$There\ are\ two\ situations:\ 1.\ A\ is\ obtained$
                                            $2.\ A\ is\ not\ obtained\ but\ B\ is\ obtained$

$1:P=0.6$

$2:P=(1-0.6)$ × $0.4=0.16$

So the probability is $ab+0.16=0.76$

I hope this helps you
