Question16:
1. Total outcomes=52
favourable outcomes=4
probability=favourable outcomes /total outcomes
=4/52
=1/13
2.TO(total outcomes) =52
FO(favourable outcomes) =26
P(red card)=FO/TO
=26/52
=1/2
3.TO=52
FO(king,queen,jack)=3*4=12
P(face card) =FO/TO
=12/52
=6/26
=3/13
4.TO=52
FO=13
P(a card of heart) =FO/TO
=13/52
=1/4
5.TO=52
FO=Total card-(king+queen)
=52-2*4
=52-8
=44
P(neither king nor queen) =FO/TO
=44/52
=22/26
=11/13
Question17:
1.TO=8+6+4=18
FO=4
P(white ball) =FO/TO
=4/18
2/9
2.TO=18
FO=6
P(black ball)=FO/TO
=6/18
=1/3
3.TO=18
FO=8
P(red ball) =FO/TO
=8/18
=4/9
4.TO=18
FO=total-red and black
=18-(8+6)
=18-14
=4
P=FO/TO
=4/18
=2/9
