multiply the nos

1×1,1×4,1×9,1×16

2×2,2×4,2×9,2×16

3×1,3×4,3×9,3×16

4×1,4×2,4×9,4×16

the probability if less than 25 is

12/36=1/3

kritika10089: why to multiply the no.s

pruthvi47: given itself in the question product of nos less than 25

kritika10089: the total outcomes are 16 and favourable outcomes are 12 so probability mut be 12/16

kritika10089: am I right??

pruthvi47: yes,i am extemly sorry

kritika10089: no total outcomes are 11

kritika10089: pls recheck

pruthvi47: u r correct
