Question

A die is thrown twice. What is the probability that
i) Square numbers come up either time
ii) 5 will come up at least once.
iii) sum of numbers appear is 10
iv) product of numbers appear is 12​

Answer 1

i) square numbers are 1;4

* no.of square night numbers if a die is thrown twice=4

probability will be =4/12

=1/3

ii)no of favourable outcomes getting 5when a die is rolled twice =2

probability=2/12

=1/6

iii)3/12=1/4

iv)4/12=1/3
