Solution:
\[\left( v \right)\] Favorable outcomes for a number less than or equal to \[9\text{ }are\text{ }1,\text{ }2,\text{ }3,\text{ }4,\text{ }5,\text{ }6,\text{ }7,\text{ }8,\text{ }9\]
So, number of favorable outcomes \[=\text{ }9\]
Hence\[,\text{ }P\left( the\text{ }pointer\text{ }will\text{ }be\text{ }at\text{ }a\text{ }number\text{ }less\text{ }than\text{ }or\text{ }equal\text{ }to\text{ }9 \right)\text{ }=\text{ }9/12\text{ }=\text{ }3/4\]
\[\left( vi \right)\] Favorable outcomes for a number between \[3\text{ }and\text{ }11\text{ }are\text{ }4,\text{ }5,\text{ }6,\text{ }7,\text{ }8,\text{ }9,\text{ }10\]
So. number of favorable outcomes \[=\text{ }7\]
Hence, P(the pointer will be at a number between \[3\text{ }and\text{ }11)\text{ }=~7/12\]
