<P>

SOLUTION :Total MEMBER `=5`
`implies` No. of ways of selecting one member `N(S)=5`
Male member `=3impliesn(M)=3`
Members over 35 YEARS of age are `P(T)=2`
Now `n(MnnT)=1`
`:.P(MuuT)=P(M)+P(T)-P(MnnT)`
`=3/5+2/5-1/5=4/5`
Here probability that the selected personwill be either male or over 35 years `=4/5`
