Hi is this for C? the answer 31/60 was correct for B
Aah I saw wrongly, so sorry.
So P(has working experience) = 31/60
P(has no working experience)=1-31/60=29/60
P(only has working experience)
=P(has experience) and P(no experience) or P(has no experience) and P(has experience)
= 31/60 x 29/60 + 29/60 x 31/60
= 899/1800
So P(has working experience) = 31/60
P(has no working experience)=1-31/60=29/60
P(only has working experience)
=P(has experience) and P(no experience) or P(has no experience) and P(has experience)
= 31/60 x 29/60 + 29/60 x 31/60
= 899/1800
ohh okay thank you so much
